Opening Ports

In order to open a port through a VPN you need to open a port with your VPN-provider.

Note: Not all VPN-providers support this feature! Notably, Mullvad does not anymore!

Note: The port present in the nixarr.vpn.wgConf, should not be used for any options!

AirVPN

Go to the ports page at AirVPN's website open a port. After opening it should look like this:

Then you can set that port for a service, for example

  nixarr.transmission = {
    enable = true;
    vpn.enable = true;
    peerPort = 12345;
  };

Debugging Ports

You can debug an open port using the [vpnTestService](https://nixarr.com/options.html#nixarr.vpn.vpntestservice.enable). If the DNS and IP checks out, it will open a netcat instance on the port specified in [vpnTestService.port](https://nixarr.com/options.html#nixarr.vpn.vpntestservice.port). You can then run:

  nc <public VPN ip> <specified port>

Where the "public VPN ip" is the one shown in the vpnTestService logs as your ip. Upon succesful connection type messages that should show up in the vpnTestService logs.
