Need help with DI-604 and VPN setup
Posted on 2006-03-20
I'm trying to setup a VPN connection through our D-Link DI-604 firewall/router to our windows 2003 server. I've fumbled my way through to being able to setup a VPN connection directly (i.e. from within our 192.168.x.x network), but when I try to connect to our external IP address I get Error 721: The remote computer did not respond.
I assume then that the server is set up okay to allow VPN connections.
This makes me then suspect either the setup or the functionality of the D-Link. There's not much to the setup - I have enabled VPN pass-through for both IPSec and PPTP, and I have set up and enabled port forwarding (IPSec: port 500 for both UDP and TCP, PPTP: port 1723 for TCP). The Firewall screen of the web-based interface says that PPTP_GRE is allowed where WAN is the source and the VPN server is the destination (shouldn't this be two-way?)
As for functionality, the D-Link has not given me any other problems outside of the VPN issue, however, after reading a large number of user reviews, it would seem that a number of others have had the same or similar experience. It's an inexpensive piece of hardware that I am not opposed to upgrading - I just want to make sure first that the problem is with it, and not me!
So, I'm a little unsure if the problem is with the setup, or with the hardware. I'm not very well-versed in these sorts of networking issues and was hoping that the whole thing would be a lot easier. I have seen a lot of general info on setting up VPN - does anyone out there have experience setting up specifically the DI-604 to allow VPN connections?
