+Deavmi's _on-the-go_
+====================
+
+## What is this?
+
+Deavmi runs a Wireguard tunneling service for client-only (meaning you won't route other's traffic) access to CRXN.
+
+The service is made available over the following networks:
+
+* Clearnet IPv6
+	* This means you can connect your Wireguard endpoint to an IPV6 host (my server)
+	* Endpoint address: `2a04:5b81:2010::65`
+* Yggdrasil
+	* This means you can run the [Yggdrasil software](http://yggdrasil-network.github.io) and use an Yggdrasil IPv6 address as the Wireguard endpoint
+	* Endpoint address: `301:754:2ca2:57f8::1`
+
+## Setup procedure
+
+### Generate the private key
+
+You need to generate a private-public key pair for your Wireguard instance.
+
+```
+wg genkey | sudo tee /etc/systemd/network/crxn0-private.key
+chmod 600 /etc/systemd/network/crxn0-private.key
+```
+
+### Fetch the public key
+
+Get the public key from it (you will need to send that to deavmi):
+
+```
+sudo cat /etc/systemd/network/crxn0-private.key | wg pubkey
+```
+
+You can then send this to `deavmi` on [BNET](/projects/bonobonet) in the `#crxn` channel. You can also shoot him an email via `deavmi@redxen.eu`.
+
+### Configure a new wireguard device
+
+```
+sudo cat > /etc/systemd/network/crxn0.netdev <<EOF
+[NetDev]
+Name = crxn0
+Kind = wireguard
+Description = wg peering with crxn over yggdrasil
+
+[WireGuard]
+PrivateKeyFile = /etc/systemd/network/crxn0-private.key
+ListenPort = 51820
+
+[WireGuardPeer]
+PublicKey = e0zNJwCyP+sD5oiF0QAkzrM3rJpmg1NeGxEHVCfBClM=
+AllowedIPs = fd00::/8
+
+# Depending on how you want to connect change the endpoint here (port remains constant)
+Endpoint = [301:754:2ca2:57f8::1]:51820
+EOF
+```
+
+### Create the crxn network configuration file
+
+```
+sudo cat > /etc/systemd/network/20-crxn0.network <<EOF
+[Match]
+Name=crxn0
+
+[Network]
+IPv6AcceptRA=false
+
+[Address]
+## Uncomment and change this to your IP address
+# Address=fdf1:1dc1:f54d:0001::1/64 # CHANGE THIS !!!!
+## Uncomment to route packets from another interface, ie eth0
+# AddPrefixRoute=false
+
+[Route]
+Destination=fd00::/8
+EOF
+```
+
+### Restart
+
+Restart the service to apply all changes
+
+```
+sudo systemctl restart systemd-networkd
+```
+

+
+I would like to thank zhoreeq for providing the configuration files above.

+CRXN _On-the-go_ ™️
+==================
+
+CRXN _On-the-go_ are a collection of services run by a few people on CRXN that have decided to lease out client-only access (meaning no bird, no routing) access to CRXN via one of their routers. Normally this will be in the form of a Wireguard endpoint that they make available to you.
+
+So far we have two people offering such services:
+
+1. [Deavmi's OTG](deavmi.md)
+2. [Rany's OTG](rany.md)

+Rany's _on-the-go_
+====================
+
+## How to use it
+
+All you need to do to get setup with Rany's On-the-go is the following (run it in your terminal):
+
+```bash
+#!/bin/sh
+
+privkey=$(wg genkey)
+pubkey=$(printf %s "$privkey" | wg pubkey)
+
+ret=$(curl -s "-Fpubkey=$pubkey" rany1.duckdns.org:5000)
+
+myaddr=$(printf %s "$ret" | jq -rc .client_address)
+serveraddr=$(printf %s "$ret" | jq  -rc .server_address)
+serverpubkey=$(printf %s "$ret" | jq -rc .server_pubkey)
+
+cat <<EOF
+[Interface]
+PrivateKey = $privkey
+Address = $myaddr/8
+MTU = 1280
+
+[Peer]
+PublicKey = $serverpubkey
+AllowedIPs = fd00::/8
+Endpoint = $serveraddr
+EOF
+```
