Good news for the VPN user....
 
GBRIDGE the Free Google VPN Connection Software is totally no limit, no adware, 100% FREE. Currently its support for Win2000/XP/Vista/Win7, and a Gmail account. Gbridge 2.0 has Google Apps support.
 
GBridge is a program that allows one Windows computer, at home for example, take control of another Windows computer which may be at school, office or anywhere. Once linked, the two computers can exchange files, upload/download information and share desktops. Gbridge is also able to traverse firewalls and NATting routers without the need for configuration. 
 
Gbridge allows you to share files, connect to and remotely control a computer using VNC, sync folders, and back up files to another computer. If you've got Google Talk/Gmail chat friends using Gbridge, the app provides the same functionality between your computer and theirs. It all sounds a little convoluted, but in effect it's a painless way for anyone to set up a VPN between computers, and assuming you've already got a Google account, it doesn't require you to sign up for anything else. 
 
Gbridge automatically forms a VPN (Virtual Private Network) among your PCs no matter where they are, regardless of whether they're behind firewall or NATting routers. This is also valuable when “assisting” people such as parents control or grandparents.
