I will soon have a file server running Debian, and this server has 2 Ethernet ports. I recently came up with the idea that one Ethernet port can come as an 'input' from my actual connection, and the other one can be an 'output' cloaked in a VPN, which would then enter a switch or router, so any computer to connect to the network through that switch or router had their connection automagically run through a VPN. Is this possible? (I don't know loads about VPNs, so sorry if I make any mistakes.)
