I would like to setup an OpenVPN server behind my Apple Airport Extreme. The Apple does not provide for a VPN, so the only way to access the home VPN server is through port forwarding, correct? Is this method recommended? Basically, I would like to access my home VPN from outside the LAN. Does my VPN server need only one LAN port, which will be connected to the Apple? Once I connect to the home VPN server will my connection be encrypted when using a public wifi? Also, can I leave my VPN server off and turn it on by sending it a wakeup packet? Sorry for all the questions, but any help will be greatly appreciated.
