Possible to have all Airport Extreme traffic go through a VPN? I'm wondering if it's possible (and if so, how to do it) set up my Airport Extreme so that all devices connecting to it have their traffic piped through a VPN. If I have an OpenVPN running on a Linux server outside my home, is it possible to route all traffic through that?
Airport running stock software doesn't have the ability to encrypt traffic on the WAN port. You could set up a server and use that connection to establish a VPN and have the AirPort WAN connect directly to the server - but that would require a computer on the local ethernet upstream of the AirPort wan port.
