VPN Tracker from Equinux is a great VPN client for the Mac platform. I use it on my MacBook when travelling in order to securely connect to my home network. This lets me access all my data at home (Windows, Linux and Mac boxes) through a secure tunnel.
So if you’ve got a Mac and one of their supported VPN Routers give their demo a try.
