I know it's an old topic, but I ran into this same problem this weekend and have managed to solve it. Here's how:

First, some facts:
I have multiple machines on a small home network. Company provided laptop was originally set to pull an IP from DHCP on the DSL-2640B. We use Cisco VPN and I have AT&T DSL (formerly SBC and before that SNET). I am based in Connecticut. DSL-2640B was installed 48 hours ago and aside from Wireless WPA2 encryption, default settings and automatic setup were used.

I had some work to complete Sunday evening and tried logging in to retrieve email first. I was able to connect to VPN without a problem and maintain a connection up to the maximum idle timeout. I could NOT access remote drives, email or remote desktops like I had been able to with my (ancient) Westell Wirespeed modem + SMC2804WBRP-G. After some brief Google queries, I hit on this thread and others similar that showed no obvious solution and decided to play around with router settings.

As I was poking around in the "Advanced" tab, I found "Virtual Server". Since I occasionally take a break to play Diablo I and II, I added those "Servers" and pointed them to my main desktop that has pulls a static IP outside the DHCP range I've set up. That got me to thinking and I did the following:

- Company provided laptop now set with a fixed IP outside the normal DHCP range.
- "Server" for IPSEC added using the default port of 500 AND the company preferred port (not 500, but not revealing either - don't want to get in trouble) and pointed to new fixed IP set on the laptop.
- Added IPSEC Server for both TCP AND UDP

Once this was done, all prior functionality over the VPN was possible - email, remote desktop, network drives, etc.

I hope this helps someone else and sorry for resurrecting an old thread.
