VPN won't work with router

[flyingace1]

This has been asked before, but I can't find a resolution.

I have a DSL modem that allows me access the MS VPN at work if I hook directly to it
with hard wire. When I connect in the router (PC to router to modem), the VPN stops
working with ERROR 619 (unable to connect to host). The odd thing is, I can connect with Cicso VPNC via the router to a different office using the Cisco product. It doesn't matter if I hard-wire or use wireless with the router.

Router is WRT54G. The OS is Windows 7 or 2000 Pro, neither work with router and both
work without it. It seems the router and VPN software don't get along. Has anyone resolved this problem?

Thanks in advance.

Check with the people at work. They may be blocking by MAC address or if they see the NAT'ing happen it might also block it.
