title: 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](https://nixarr.com/options.html#nixarr.vpn.wgconf),
|
|
> should not be used for any options!
|
|
|
|
## AirVPN
|
|
|
|
Go to the [ports page](https://airvpn.org/ports/) 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
|
|
|
|
```nix {.numberLines}
|
|
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:
|
|
|
|
```sh
|
|
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.
