I have a Windows Server 2003 box installed on an ESXi server (with a bridged connection) connected to a Linksys RV042 router. The Server 2003 install is configured with the RRAS role. I think my policy is set correctly since I can connect to it directly across the LAN. My RV042 is forwarding TCP port 1723 to the Server 2003 box (and I've also tried putting the Server 2003 box on the DMZ). I don't see any options to forward GRE, but following these instructions about disabling the SPI, I had hope.
Nonetheless, I'm unable to connect to the VPN over the WAN.
portqry tells me the box is listening on 1723, but I still get an error 800 when I try to connect myself.
Any tips on trying to troubleshoot this?
Update: Just also wanted to mention that under "VPN Passthrough" the "PPTP Pass through" et al are Enabled.
