Remote interface over WAN - what Port to forward?

[skycamel]

I would like to be able to connect to my rAudio interface when outside the house. When I'm connected to my LAN I just give the IP-address without port number and I get the interface. But when outside the house I will have to forward a port to my RPI IP but which port?

80/TCP

I suggest you to use a VPN to enter the house.
Exposing on the Internet a local application is not a wise choice, IMHO.

My LAN router has a VPN client to a VPN provider (actually to my OpenVPN access server which I manage with my private CA, kept offline) and it routes between its local LAN and the VPN subnet.
On my android tablet I have a VPN client connected to the same VPN provider.
That way I can access all the local LAN services when I'm not directly connected to the router.
It is possible to install a VPN client on the same RPI with rAudio, so to avoid LAN routing.

Thank you very much for your insight. I'm a noob what VPN is concerned so if you could give me some more info how to do this I would appreciate that. I'm using Windscribe.

@fscara figured out myself.
In my router I created a VPN server to which I connect when I'm outside and I can reach whatever is on the LAN.
Thanks for the tip

I'm sorry having lost your request for more info, I don't access a computer every day.
I'm also happy that you figured out yourself, a solution you don't know how it works is not a really good solution.
