* `SERVER_HOST`: The host name of your server
* `SERVER_PORT`: The port the service should listen at
* `NETWORK`: Some custom /24 network. e.g. `192.168.42.0`
* `NETWORK`: Some custom /24 network. Defaults to `192.168.42.0`
* `MTU`: MTU to be used. Use default wireguard MTU if not set.
* `CLIENTS`: Number of clients for which configurations are to be created. Do not use more than 240 clients.
* `DISABLE_FORWARD_ALL_TRAFFIC`: Use `true` or `yes` to not add iptables rules and do not forward all traffic.
