I will share my setup which I think is close to what you want to achieve: 1. I have created two devices in the Client Area -> VPN Devices: 2. I forwarded ports and assigned them to devices: 3.a In Eddie a drop-down menu appeared (you may need to re-login in the app) and I selected the device: 3.b For the other device I used config generator (in the Client Area) and I selected the other device in the menu. With this setup I can connect to the same VPN server on both PC and Laptop and the port forwarding works because system knows which ports to open for each connection/device.
Of course there is no need to do all this if both devices connect to different servers.
The default behavior if I recall is that the newest connection to that VPN server will override the port forwarding rules for older connection(s).
Result:
PS.
Kudos to AirVPN for having the most flexible port forwarding system on the market 😉
