BleepingComputer.com: VPN Error 619 with New Linksys/Cisco RVL200

Hello all,
We recently upgraded to a business class router at our office, the Linksys RVL200. After installation some of the VPN connections are not able to connect. We have tried changing quite a few settings on the new router as well as DMZ'ing the router on the other end to allow all traffic to be forwarded with no luck. What is strange is that some can connect on the same ISP as others can not. It doesn't seem to be user specific either as they can be logged in at other locations.

Server 2003 in the office.
Windows XP Pro on the remote stations
Linksys RVL200
3 out of 7 VPN connections don't work.
we have deleted and reinstalled the VPN connection.

Any ideas on what may be happening?
Thank you,
Michael
