iPig

iPig does the same as Google Wifi does, but offers an OPTIONAL server component as well, so you can set up your own VPN server.



Unlike OpenVPN it is _really_ easy to use.

It has the option to block your traffic if you are not connected to VPN - so you do not check your email by mistake without using the iPig VPN.



Openvpn

OpenVpn is easy to configure, even with pubic key encryption, and is even easier to setup than IPSec, which uses a rather obtuse key management system.
