# Intro
-Over the last 8+ years I've tried a wide range of VPN solutions. Somewhat out of necessity, since the city I was living in was behind the Great Wall of China. Everything from old-school PPTP to crazy round-robin GoAgent AppEngine proxy setups were common back in the early 2010's to break through the GFW, these days it's mostly OpenVPN, StealthVPN, IPSec/IKEv2 and others. From the recommendation of a few people in the [RC](https://recurse.com) Zulip community, I decided to try WireGuard and was surprised to find it checked almost all the boxes.
+Whether living behind the Great Wall of China or just trying to form a network between your servers, WireGuard is a great option and serves as a "lego block" for building networks (much in the same way that ZFS is a lego block for building filesystems).
-## My Personal Requirements for a VPN Solution
+## WireGuard Overview
- - minimal config, low config surface area and few exposed tunables
- - minimal key management overhead, 1 or 2 preshared keys or certs is ok, but ideally not both
- - ability to easily create a LAN like 10.0.0.0/24 between all my servers, every peer can connect to every peer,
- - ability to bust through NATs with a signalling server, routing nat-to-nat instead of through a relay (WebRTC-style)
- - fallback to relay server when nat-to-nat busting is unavailable or unreliable
- - ability to route to a fixed list of ips/hosts with 1 keypair per host (not needed, but nice to have: ability to route arbitrary local traffic or *all* internet traffic to a given host)
+ - minimal config, low tunable surface area and sane defaults
+ - minimal key management work needed, just 1 public & 1 private key per host
+ - behaves like a normal ethernet interface, behaves well with standard kernel packet routing rules
+ - ability to easily create a LAN like 192.0.2.0/24 between all servers, or more complex networks using custom routes
+ - ability to some traffic or all traffic to/through arbitrary hosts on the VPN LAN
- robust automatic reconnects after reboots / network downtime / NAT connection table drops
- - fast (lowest possible latency and line-rate bandwidth)
- - encrypted, and secure by default (not needed, nice to have: short copy-pastable key pairs)
+ - fast (low latency and line-rate bandwidth)
+ - modern encryption, secure by default with forward secrecy & resilience to downgrade attacks
- ideally support for any type of Level 2 and control traffic, e.g. ARP/DHCP/ICMP (or ideally raw ethernet frames), not just TCP/HTTP
- - ability to join the VPN from Ubuntu, FreeBSD, iOS, macOS (Windows/Android not needed but would be nice)
- - not a requirement, but ideally it would support running in docker with a single container, config file, and preshared key on each server, but with a full network interface exposed to the host system (maybe with tun/tap on the host passing traffic to the container, but ideally just a single container + config file without outside dependencies)
+ - ability to join the VPN from Ubuntu, FreeBSD, iOS, MacOS, Windows, Android (via open-source apps or natively)
+ - supports both running on the host routing traffic for docker or running in a docker container routing for the host
+
+**Things WireGuard does not do:**
+
+- form a self-healing mesh network where nodes automatically gossip with neighbors
+- break through double NATs with a signalling server (WebRTC-style)
+- handle automatically distributing & revoking keys through a central authority
+- allow sending raw layer-2 ethernet frames (it's at the IP layer)
+
+But you can write your own solutions for these problems using WireGuard under the hood (like [Tailscale](https://github.com/tailscale/tailscale) or [AltheaNet](https://althea.net/)).
-## List of Possible VPN Solutions
+## List of Other VPN Solutions
+ - [WireGuard](https://www.wireguard.com/)
+ - [IPSec (IKEv2)](https://github.com/jawj/IKEv2-setup)/strongSwan: in my experience, there was lots of brittle config that was different for each OS, the NAT busting setup is very manual and involves updating the central server and starting all the others in the correct order, it wasn't great at becoming stable again after network downtime, had to be manually restarted often. your mileage may vary.
+ - [OpenVPN](https://openvpn.net/vpn-server-resources/site-to-site-routing-explained-in-detail/): can work over UDP or be disguised as HTTPS traffic over TCP
+ - StealthVPN: haven't tried it, should I?
+ - [DsVPN](https://github.com/jedisct1/dsvpn): I think it does TCP-over-TCP which usually doesn't end well...
+ - [SoftEther](https://www.softether.org/) ([SSTP](https://en.wikipedia.org/wiki/Secure_Socket_Tunneling_Protocol)): haven't tried it yet, should I? (also does TCP-over-TCP?)
+ - L2TP: somewhat outdated
- PPTP: ancient, inflexible, insecure, doesn't solve all the requirements
- - L2TP: meh
- - SOCKS: proxy tunnel, not a VPN, not great for this use case
- - [IPSec (IKEv2)](https://github.com/jawj/IKEv2-setup)/strongSwan: lots of brittle config that's different for each OS, NAT busting setup is very manual and involves updating the central server and starting all the others in the correct order, not great at reconnecting after network downtime, had to be manually restarted often
- - [TINC](https://www.tinc-vpn.org/): haven't tried it yet, but it doesn't work on iOS, worst case scenario I could live with that if it's the only option
- - [OpenVPN](https://openvpn.net/vpn-server-resources/site-to-site-routing-explained-in-detail/): I don't like it from past experience but could be convinced if it's the only option
- - StealthVPN: haven't tried it

### Subnet
-A group of IPs separate from the public internet, e.g. 10.0.0.1-255 or 192.168.1.1/24. Generally behind a NAT provided by a router, e.g. in office internet LAN or a home WiFi network.

### CIDR Notation
A way of defining a subnet and its size with a "mask", a smaller mask = more address bits usable by the subnet & more IPs in the range. Most common ones:
- + `10.0.0.1/32` (a single ip address, `10.0.0.1`) netmask = `255.255.255.255`
- + `10.0.0.1/24` (255 ips from `10.0.0.1`-`255`) netmask = ` 255.255.255.0`

-To people just getting started `10.0.0.1/32` may seem like a weird and confusing way to refer to a single IP. This design is nice though because it allows peers to expose multiple IPs if needed without needing multiple notations. Just know that anywhere you see something like `10.0.0.3/32`, it really just means `10.0.0.3`.

## How WireGuard Works
### How Public Relay Servers Work
-Public relays are just normal VPN peers that are able to act as an intermediate relay server between any VPN clients behind NATs, they can forward any VPN subnet traffic they receives to the correct peer at the system level (WireGuard doesn't care how this happens, it's handled by the kernel `net.ipv4.ip_forward = 1` and the iptables routing rules).

If all peers are publicly accessible, you don't have to worry about special treatment to make one of them a relay server, it's only needed if you have any peers connecting from behind a NAT.
-Each client only needs to define the publicly accessible servers/peers in it's config, any traffic bound to other peers behind NATs will go to the catchall VPN subnet (e.g. `10.0.0.1/24`) in the public relays `AllowedIPs` route and will be forwarded accordingly once it hits the relay server.

More complex topologies are definitely achievable, but these are the basic routing methods used in typical WireGuard setups:
- **Direct node-to-node**
- In the best case, the nodes are on the same LAN or are both publicly accessible, and traffic will route over encrypted UDP packets sent directly between the nodes.
+ In the simplest case, the nodes will either be on the same LAN or both be publicly accessible. Define directly accessible nodes with hardcoded `Endpoint` addresses and ports so that WireGuard can connect straight to the open port and route UDP packets without intermediate hops.
- **Node behind local NAT to public node**
- When 1 of the 2 parties is behind a remote NAT (e.g. when laptop behind a NAT connects to `public-server2`), the connection will be opened from NAT -> public client, then traffic will route directly between them in both directions as long as the connection is kept alive.
-- **Node behind local NAT to node behind remote NAT (via UDP NAT hole-punching)**
- "Hole Punching" refers to triggering automatic NAT rules of a router in order to allow inbound traffic. When you send a UDP packet out, the router (usually) creates a temporary rule mapping your source address and port to the destination address and port, and vice versa. This is how most UDP applications function behind NATs (e.g. Bittorent, Skype, etc). UDP packets returning from the destination address and port (and no other) are passed through to the original source address and port (and no other). This rule will timeout after some minutes of inactivity, so the client behind the NAT must send regular outgoing packets to keep it open (see `PersistentKeepalive`).
- Getting this to work when both end-points are behind NATs or firewalls would require that both end-points send packets to each-other at about the same time. This means that both sides need to know each-other's public IP addresses and port numbers and need to communicate this to each-other by some other means (in our case by defining them in `wg0.conf`).
- WireGuard punches holes through NATs natively as a side effect of its UDP-based design, but it only works if a `ListenPort` is hardcoded for the peer behind the NAT. It does not search for a hole-punching port dynamically like WebRTC/N2N as it has no concept of a signaling server to communicate the port to the other side, it only works with a hardcoded port and `PersistentKeepalive` set to some non-null value.
+ When 1 of the 2 parties is behind remote NAT (e.g. when a laptop behind NAT connects to `public-server2`), define the publicly accessible node with a hardcoded `Endpoint` and the NAT-ed node without. The connection will be opened from NAT client -> public client, then traffic will route directly between them in both directions as long as the connection is kept alive by outgoing `PersistentKeepalive` pings from the NAT-ed client.
- **Node behind local NAT to node behind remote NAT (via relay)**
- In the worst case when both parties are behind remote NATs, both will open a connection to `public-server1`, and traffic will forward through the intermediary bounce server as long as the connections are kept alive.
-
-
-Choosing the proper routing method is handled automatically by WireGuard as long as at least one server is acting as a public relay with `net.ipv4.ip_forward = 1` enabled, and clients have `AllowIPs = 10.0.0.1/24` set in the relay server `[peer]` (to take traffic for the whole subnet).
+ Most of the time when both parties are behind NATs, the NATs do source port randomization making direct connections infeasible, so they will both have to open a connection to `public-server1`, and traffic will forward through the intermediary bounce server as long as the connections are kept alive.
+- **Node behind local NAT to node behind remote NAT (via UDP NAT hole-punching)**
+ While sometimes possible, it's generally infeasible to do direct NAT-to-NAT connections on modern networks, because most NAT routers are quite strict about randomizing the source port, making it impossible to coordinate an open port for both sides ahead of time. Instead, a signaling server (STUN) must be used that stands in the middle and communicates which random source ports are assigned to the other side. Both clients make an initial connection to the public signaling server, then it records the random source ports and sends them back to the clients. This is how WebRTC works in modern P2P web apps. Even with a signalling server and known source ports for both ends, sometimes direct connections are not possible because the NAT routers are strict about only accepting traffic from the original destination address (the signalling server), and will require a new random source port to be opened to accept traffic from other IPs (e.g. the other client attempting to use the originally communicated source port). This is especially true for "carrier-grade NATs" like cellular networks and some enterprise networks, which are designed specifically to prevent this sort of hole-punching connection. See the full section below on [**NAT to NAT Connections**](#NAT-to-NAT-Connections) for more information.
-More specific (also usually more direct) routes provided by other peers will take precedence when available, otherwise traffic will fall back to the least specific route and use the `10.0.0.1/24` catchall to forward traffic to the bounce server, where it will in turn be routed by the relay server's system routing table back down the VPN to the specific peer that's accepting routes for that traffic.

WireGuard does not automatically find the fastest route or attempt to form direct connections between peers if not already defined, it just goes from the most specific route in `[Peers]` to least specific.

+Technically, multiple servers can share the same private key as long as clients arent connected to two servers with the same key simulatenously.
+An example of a scenario where this is a reasonable setup is if you're using round-robin DNS to load-balance connections between two servers that are pretending to be a single server.

Overview of the general process:
1. Install `apt install wireguard` or `pkg/brew install wireguard-tools` on each node
2. Generate public and private keys locally on each node `wg genkey`+`wg pubkey`
-3. Create a `wg0.conf` wireguard config file on the main relay server
- - `[Interface]` Make sure to specify a CIDR range for the entire VPN subnet when defining the address the server accepts routes for `Address = 10.0.0.1/24`
+3. Create a `wg0.conf` WireGuard config file on the main relay server
+ - `[Interface]` Make sure to specify a CIDR range for the entire VPN subnet when defining the address the server accepts routes for `Address = 192.0.2.1/24`
- `[Peer]` Create a peer section for every client joining the VPN, using their corresponding remote public keys
4. Create a `wg0.conf` on each client node
- - `[Interface]` Make sure to specify only a single IP for client peers that don't relay traffic `Address = 10.0.0.3/32`.
- - `[Peer]` Create a peer section for each public peer not behind a NAT, make sure to specify a CIDR range for the entire VPN subnet when defining the remote peer acting as the bounce server `AllowedIPs = 10.0.0.1/24`. Make sure to specify individual IPs for remote peers that don't relay traffic and only act as simple clients `AllowedIPs = 10.0.0.3/32`.
-5. Start wireguard on the main relay server with `wg-quick up /full/path/to/wg0.conf`
-6. Start wireguard on all the client peers with `wg-quick up /full/path/to/wg0.conf`
-7. Traffic is routed from peer to peer using most optimal route over the WireGuard interface, e.g. `ping 10.0.0.3` checks for local direct route first, then checks for route via public internet, then finally tries to route by bouncing through the public relay server.

## Config Reference
+### Overview
+
+WireGuard config is in [INI syntax](https://en.wikipedia.org/wiki/INI_file), defined in a file usually called `wg0.conf`. It can be placed anywhere on the system, but is often placed in `/etc/wireguard/wg0.conf`.
+
+The config path is specified as an argument when running any `wg-quick` command, e.g:
+`wg-quick up /etc/wireguard/wg0.conf` (always specify the full, absolute path)
+
+The config file name must be in the format `${name of the new WireGuard interface}.conf`. WireGuard interface names are typically prefixed with `wg` and numbered starting at `0`, but you can use any name that matches the regex `^[a-zA-Z0-9_=+.-]{1,15}$`.
+
+Config files can opt to use the limited set of `wg` config options, or the more extended `wg-quick` options, depending on what command is preferred to start WireGuard. These docs recommend sticking to `wg-quick` as it provides a more powerful and user-friendly config experience.

### NAT To NAT Connections
-WireGuard can natively make connections between two clients behind NATs, without need of a public relay server. This is achieved by hardcoding a `ListenPort` on both sides (and enabling `PersistentKeepalive`) so that both peers don't need a separate publicly-accesible signaling server to determine where to send the initial UDP packets.
+WireGuard can sometimes natively make connections between two clients behind NATs without the need for a public relay server, but in most cases this is not possible. NAT-to-NAT connections are only possible if at least one host has a stable, publicly-accessible IP address:port pair that can be hardcoded ahead of time, whether that's using a FQDN updated with Dynamic DNS, or a static public IP with a non-randomized NAT port opened by outgoing packets, anything works as long as all peers can communicate it beforehand and it doesn't change once the connection is initiated.
+
+A known port and address need to be configured ahead of time because WireGuard doesn't have a signalling layer or public STUN servers that can be used to search for other hosts dynamically. WebRTC is an example of a protocol that can dynamically configure a connection between two NATs, but it does this by using an out-of-band signaling server to detect the IP:port combo of each host. WireGuard doesn't have this, so it only works with a hardcoded `Endpoint` + `ListenPort` (and `PersistentKeepalive` so it doesn't drop after inactivity).
+
+#### Requirements for NAT-to-NAT setups
+
+ - At least one peer has to have to have a hardcoded, directly-accessible `Endpoint` defined. If they're both behind NATs without stable IP addresses, then you'll need to use Dynamic DNS or another solution to have a stable, publicly accessibly domain/IP for at least one peer
+ - At least one peer has to have a hardcoded UDP `ListenPort` defined, and it's NAT router must not do UDP source port randomization, otherwise return packets will be sent to the hardcoded `ListenPort` and dropped by the router, instead of using the random port assigned by the NAT on the outgoing packet
+ - All NAT'ed peers must have `PersistentKeepalive` enabled on all other peers, so that they continually send outgoing pings to keep connections persisted in their NAT's routing table
-The connection process looks like this:
+#### The hole-punching connection process
1. Peer1 sends a UDP packet to Peer2, it's rejected Peer2's NAT router immediately, but that's ok, the only purpose was to get Peer1's NAT to start forwarding any expected UDP responses back to Peer1 behind its NAT
- 2. Peer2 sends a UDP packet to Peer1, it's accepted and fowarded to Peer1 as Peer1's NAT server is already expecting responses from Peer2 because of the initial outgoing packet
+ 2. Peer2 sends a UDP packet to Peer1, it's accepted and forwarded to Peer1 as Peer1's NAT server is already expecting responses from Peer2 because of the initial outgoing packet
3. Peer1 sends a UDP response to Peer2's packet, it's accepted and forwarded by Peer2's NAT server as it's also expecting responses because of the initial outgoing packet
This process of sending an initial packet that gets rejected, then using the fact that the router has now created a forwarding rule to accept responses is called "UDP hole-punching".
-When you send a UDP packet out, the router (usually) creates a temporary rule mapping your source address and port to the destination address and port, and vice versa. UDP packets returning from the destination address and port (and no other) are passed through to the original source address and port (and no other). This is how most UDP applications function behind NATs (e.g. Bittorent, Skype, etc). This rule will timeout after some minutes of inactivity, so the client behind the NAT must send regular outgoing packets to keep it open (see `PersistentKeepalive`).

This is how most UDP applications function behind NATs (e.g. BitTorrent, Skype, etc). This rule will timeout after some minutes of inactivity, so the client behind the NAT must send regular outgoing packets to keep it open (see `PersistentKeepalive`).
+
+Getting this to work when both end-points are behind NATs or firewalls requires that both end-points send packets to each-other at about the same time. This means that both sides need to know each-other's public IP addresses and port numbers ahead of time, in WireGuard's case this is achieved by hard-coding pre-defined ports for both sides in `wg0.conf`.
+
+#### Drawbacks and limitations
+
+As of 2019, many of the old hole-punching methods used that used to work are no longer effective. One example was a novel method pioneered by [pwnat](https://github.com/samyk/pwnat) that faked an ICMP Time Exceeded response from outside the NAT to get a packet back through to a NAT'ed peer, thereby leaking its own source port. Hardcoding UDP ports and public IPs for both sides of a NAT-to-NAT connection (as described above) still works on a small percentage of networks. Generally the more "enterprisey" a network is, the less likely you'll be able to hole punch public UDP ports (commercial public Wi-Fi and cell data NATs often don't work for example).
+
+##### Source port randomization
+
+NAT-to-NAT connections are not possible if all endpoints are behind NAT's with strict UDP source port randomization (e.g. most cellular data networks). Since neither side is able to hardcode a `ListenPort` and guarantee that their NAT will accept traffic on that port after the outgoing ping, you cannot coordinate a port for the initial hole-punch between peers and connections will fail. For this reason, you generally cannot do phone-to-phone connections on LTE/3g networks, but you might be able to do phone-to-office or phone-to-home where the office or home has a stable public IP and doesn't do source port randomization.
+
+##### Using a signaling server
-Getting this to work when both end-points are behind NATs or firewalls would require that both end-points send packets to each-other at about the same time. This means that both sides need to know each-other's public IP addresses and port numbers and need to communicate this to each-other by some other means (in our case by hard-coding them in `wg0.conf` in advance). WebRTC requires a STUN signaling server to communicate the hole-punching port because it would be impossible for browsers to hardcode listening ports for all possible connections in advance.
+NAT-to-NAT connections from behind NATs with strict source-port randomization is possible, you just need a signaling server to tell each side the other's IP:port tuple. Here are a few implementations that achieve this with WireGuard:
-WireGuard punches holes through NATs natively as a side effect of it's UDP-based design, but it only works if a `ListenPort` is hardcoded for the peer behind the NAT. It does not search for a hole-punching port dynamically like WebRTC/N2N as it has no concept of a signaling server to communicate the port to the other side, it only works with a hardcoded port and `PersistentKeepalive` set to some non-null value on both sides.
+- https://github.com/takutakahashi/wg-connect
+- https://git.zx2c4.com/wireguard-tools/tree/contrib/nat-hole-punching/
-This approach has some limitations, which is why having a fallback public relay server is still advised, see:
+##### Dynamic IP addresses
+Many users report having to restart WireGuard whenever a dynamic IP changes, as it only resolves hostnames on startup. To force WireGuard to re-resolve dynamic DNS `Endpoint` hostnames more often, you may want to use a `PostUp` hook to restart WireGuard every few minutes or hours.
+
+#### Testing it out
+
+You can see if a hole-punching setup is feasible by using netcat on the client and server to see what ports and connection order work to get a bidirectional connection open: run `nc -v -u -p 51820 51820` (on peer1) and `nc -v -u -l 0.0.0.0 51820` (on peer2), then type in both windows to see if you can get bidirectional traffic going. If it doesn't work regardless of which peer sends the initial packet, then WireGuard won't be unable to work between the peers without a public relay server.

+NAT-to-NAT connections are often more unstable and have other limitations, which is why having a fallback public relay server is still advised.

-# Example Server-To-Server Config with Roaming Devices
-
-The complete example config for the setup below can be found here: https://github.com/pirate/wireguard-docs/tree/master/full-example (WARNING: do not use it on your devices without changing the public/private keys!).
-
-## Overview
-
-### Network Topology
-
-These 5 devices are used in our example setup to explain how WireGuard supports bridging across a variety of network conditions, they're all under an example domain `example-vpn.dev`, with the following short hostnames:
-
-- `public-server1` (not behind a NAT, acts as the main VPN bounce server)
-- `public-server2` (not behind a NAT, joins as a peer without bouncing traffic)
-- `home-server` (behind a NAT, joins as a peer without bouncing traffic)
-- `laptop` (behind NAT, sometimes shared w/ home-server/phone, sometimes roaming)
-- `phone` (behind NAT, sometimes shared w/ home-server/laptop, sometimes roaming)
+WireGuard can be run in Docker with varying degrees of ease. In the simplest case, `--privileged` and `--cap-add=all` arguments can be added to the docker commands to enable the loading of the kernel module.
-### Explanation
+Setups can get somewhat complex and are highly dependent on what you're trying to achieve. You can have WireGuard itself run in a container and expose a network interface to the host, or you can have WireGuard running on the host exposing an interface to specific containers.
-This VPN config simulates setting up a small VPN subnet `10.0.0.1/24` shared by 5 nodes. Two of the nodes (public-server1 and public-server2) are VPS instances living in a cloud somewhere, with public IPs accessible to the internet. home-server is a stationary node that lives behind a NAT with a dynamic IP, but it doesn't change frequently. Phone and laptop are both roaming nodes, that can either be at home in the same LAN as home-server, or out-and-about using public wifi or cell service to connect to the VPN.
+See below for an example of a Docker container `vpn_test` routing all its traffic through a WireGuard relay server.
-Whenever possible, nodes should connect directly to each other, depending on whether nodes are directly accessible or NATs are between them, traffic will route accordingly:
+#### Example Relay Server Setup
-### The Public Relay
+```yaml
+version: '3'
-`public-server1` acts as an intermediate relay server between any VPN clients behind NATs, it will forward any 10.0.0.1/24 traffic it receives to the correct peer at the system level (WireGuard doesn't care how this happens, it's handled by the kernel `net.ipv4.ip_forward = 1` and the iptables routing rules).
-
-Each client only needs to define the publicly accessible servers/peers in it's config, any traffic bound to other peers behind NATs will go to the catchall `10.0.0.1/24` for the server and will be forwarded accordingly once it hits the main server.
-
-In summary: only direct connections between clients should be configured, any connections that need to be bounced should not be defined as peers, as they should head to the bounce server first and be routed from there back down the vpn to the correct client.
-
-## Full Example Code
-
-To run this full example, simply copy the `full wg0.conf config file for node` section from each node onto each server, enable IP forwarding on the public relay, and then start WireGuard on all the machines.
-
-For more detailed instructions, see the [Quickstart](#Quickstart) guide and API reference above.

+# Example Server-To-Server Config with Roaming Devices
+
+WARNING: **Make sure to change the IP addresses and ranges in your configs before running!**
+The blocks used in these examples are reserved for documentation purposes by the IETF and should never be used in real network setups.
+
+ - **`192.0.2.0/24`** (TEST-NET-1) IPv4 example range [RFC5737](https://tools.ietf.org/html/rfc5737)
+ - **`2001:DB8::/32`** IPv6 example range [RFC3849](https://tools.ietf.org/html/rfc3849)
+
+You can use any private range you want instead, e.g. `10.0.44.0/24`, just make sure
+it doesn't conflict with any of the LAN subnet ranges your peers are on.
+
+The complete example config for the setup below can be found here: https://github.com/pirate/wireguard-docs/tree/master/full-example (WARNING: do not use it on your devices without changing the public/private keys!).
+
+## Overview
+
+### Network Topology
+
+These 5 devices are used in our example setup to explain how WireGuard supports bridging across a variety of network conditions, they're all under an example domain `example-vpn.dev`, with the following short hostnames:
+
+- `public-server1` (not behind a NAT, acts as the main VPN bounce server)
+- `public-server2` (not behind a NAT, joins as a peer without bouncing traffic)
+- `home-server` (behind a NAT, joins as a peer without bouncing traffic)
+- `laptop` (behind NAT, sometimes shared w/ home-server/phone, sometimes roaming)
+- `phone` (behind NAT, sometimes shared w/ home-server/laptop, sometimes roaming)
+
+### Explanation
+
+This VPN config simulates setting up a small VPN subnet `192.0.2.1/24` shared by 5 nodes. Two of the nodes (public-server1 and public-server2) are VPS instances living in a cloud somewhere, with public IPs accessible to the internet. home-server is a stationary node that lives behind a NAT with a dynamic IP, but it doesn't change frequently. Phone and laptop are both roaming nodes, that can either be at home in the same LAN as home-server, or out-and-about using public wifi or cell service to connect to the VPN.
+
+Whenever possible, nodes should connect directly to each other, depending on whether nodes are directly accessible or NATs are between them, traffic will route accordingly:
+
+### The Public Relay
+
+`public-server1` acts as an intermediate relay server between any VPN clients behind NATs, it will forward any 192.0.2.1/24 traffic it receives to the correct peer at the system level (WireGuard doesn't care how this happens, it's handled by the kernel `net.ipv4.ip_forward = 1` and the iptables routing rules).
+
+Each client only needs to define the publicly accessible servers/peers in its config, any traffic bound to other peers behind NATs will go to the catchall `192.0.2.1/24` for the server and will be forwarded accordingly once it hits the main server.
+
+In summary: only direct connections between clients should be configured, any connections that need to be bounced should not be defined as peers, as they should head to the bounce server first and be routed from there back down the vpn to the correct client.
+
+## Full Example Code
+
+To run this full example, simply copy the `full wg0.conf config file for node` section from each node onto each server, enable IP forwarding on the public relay, and then start WireGuard on all the machines.
+
+For more detailed instructions, see the [Quickstart](#Quickstart) guide and API reference above. You can also download the complete example setup here: https://github.com/pirate/wireguard-docs/tree/master/full-example (WARNING: do not use it on your devices without changing the public/private keys!).
