BBB as VPN relay server

Hello Beagleboners!

So I have at home the Amaon Fire TV box and one of the problems is that I would like to use it with VPN in place to avoid some geo restrictions. As far as my googling goes you cannot do this directly on the fire TV box

My thought is using a beaglebone in between to provide a VPN. So the setup would be:

Amazon fire TV → lan → Beaglebone Black → via VPN into the internet

Is something like this possible? I could imagine adding some buttons or something so that you can chose easily if you want to have the VPN on and if so to which country you want to go.

Any pointers would be appreciated!
