Connect from PC to Air Router Tunnel Server

The easiest "Best" method that we implement is to use another AirRouter configured as a AREDN MESH Tunnel Client attached to your PC.  Easy setup and you can take it anywhere you have an internet connection available via Ethernet.  Add a regular Wi-Fi Access Point to the AirRouter and you can connect to public Wi-Fi systems and tunnel back into your system.  There may also be a way to do this with a RPi device, but the setup is a bit more advanced, having to add OLSR, VTUN modules and the like.
