We have a 2003 Windows domain and I was just trying to set up a pretty simple pptp vpn server. I enabled RRAS (routing and remote access) and set up a vpn gateway. The wizard asked me which network adapter was used for local and which one was used for internet connections. Both network adapters have a 10.1.x.x/16 address on them and connect to the same router under the same VLAN (we only have one vlan by default). After I finished the wizard, I can no longer connect to the box. Pulled up the console and I couldn't ping any server by IP because of "Destination could not be reached" error. I ran a "netstat -rn" command and all the routes seem to look ok, so I can't imagine why that was a problem.
Is there additional configuration I need to do do in rras afterward? I always thought it was a pretty easy setup. I originally didn't set it up on a domain controller, but rather a Windows 2000 server. But even when installed on a 2003 domain controller, same problem there. Why does enabling rras totally bring down the machines network connectivity?
