  2. Hi. I use AirVPN in Ubuntu's network manager and would like to use it as tap0, as opposed to tun0, so that I can bridge my connection via ethernet cable to another device (one which is not as easy to configure) and have it connect to the Internet the same way a virtual machine would (i. e. connecting through AirVPN the way my PC would). Unfortunately, I have found no way to bridge (or otherwise sharee) the connection besides using a TAP device. However, upon changing the .ovpn files from 'dev tun' and 'persist-tun' to 'dev tap' and 'persist-tap', I have found that I am unable to access the Internet. There doesn't seem to be a whole lot out there on sharing a VPN connection via Ubuntu, so I'd appreciate any suggestions that you might have for me. Oh, and if this is possible, I wonder why AirVPN files pick TUN over TAP. Is it in any way safer? Would I be compromising security in this case to get a little more functionality?
