Q:  Disconnects with error 721

I'm having trouble trying to figure this one out. I have enabled and configured RRAS on a win2k box running AD. Internet connection is provided by DSL to a Linksys firewall, which have the proper ports enabled and are being forwarded to the Win2k server. When I dial to a separate ISP, then run the XP Pro created VPN connection, it starts to connect...gets to verifying username/pw, then disconnects with error 721.

I am unable to ping the static IP of the DSL router or connect to the Linksys configuration page, but am able to ping the IP of the DSL providers main DNS server.

A: Souns like GRE issue.this page may  help, http://www.chicagotech.net/VPN%20process.htm
