I have a VPN server running on Windows Server 2003. I have port 1723 forwarded so that users can connect to the vpn through the firewall from the internet. VPN connectivity is not my problem. When I try to ping my mail server while on the VPN, it is not using the internal IP address, it is wanting to go to the external IP address. I have AT&T managed internet service and have a host record on AT&T DNS servers for the external IP. What I don't understand is why it is not using my internal DNS servers to resolve this. I have verified that once connected to VPN the computer is using my internal DNS servers to resolve this name.
