Windows 2003 server not working with Linksys router
Posted on 2006-05-23
I have Windows 2003 server I am trying to implement a VPN to through a Linksys WRT54GS router using VPN Pass Through. The VPN is set up to use PPTP. When I test the VPN without the router (the server is directly connected to the cable modem), I can connect to the VPN every time. When I put the router back in place, I get an "Error 678: there was no answer."
I have used Linksys tech support and they have walked me through all of the options to make passthrough work and have even administered the router remotely to configure the router themselves and they cannot figure out the problem.
The following are already in place:
PPTP is enabled
The following ports are forwarded to the VPN server in Port Forwarding:
47, 50, 500, 1723
We have also tried:
Port Triggering instead of port forwarding.
Placing the server in the DMZ
Nothing seems to work. I still have an outstanding ticket with level 2 tech support but if anyone has any suggestions I am willing to try most anything.
If it helps, I have a similar problem with a Netgear router but want to focus on the Linksys since it is critical and time sensitive. I am open to the possibility that there is a misconfiguration problem on the server but it does not seem likely since I can always connect when the router is taken out of the equation.
