We have a Windows 2003 Advanced Server. It currently accepts VPN connections, and works great.
However, we're setting up a new office. It will need to have 2 or more people using the VPN connection at the same time, from behind the same cable modem/router. Is this possible?
The new office has a cable modem (Motorola SBG900) which doubles as a wireless gateway/router. All of the client computers will be connecting through that connection.
I've tried just creating VPN connections on both client computers, but that doesn't work. I can log onto the VPN with computer A just fine...but every time I try to log computer B on, it causes computer A to stop working. Computer A appears to be connected...but no resources are available, no ping, etc. Even when I disconnect both, computer A can't log back on (it connects to the remote IP, tries to verify username and password, and returns a 721 error). It takes several minutes before computer A can log back on.
Thanks for all your help,
