I just completed a "Swing Migration" of a 2003 SBS Premium Server. Everything went relatively smooth except I can't get VPN to work now. The new server name is the SAME as well as the IP address of the previous server, so the Fortigate Firewall programming should be right. VPN worked to the previous server fine.
I went through the wizards CEICW and "Configure Remote Access" and they went through without a hitch. The server has only 1 NIC (just as the prior server did).
When I try to connect, the client gets "Error 800" stating that it can't find the server.
I CAN VPN internally to the server, however, externally it doesn't work.
Keep in mind that the NEW server has the SAME IP address and the SAME DNS Name so the Fortigate Firewall should be configured correctly.
I know it sounds like the firewall is blocking, however, it is configured correctly.
We are NOT running ISA on the server.
Any help would be GREATLY appreciated!
