Sacred Gold

I am trying to play Sacred Gold over a LAN. I have a workstation and a laptop. When I start a multiplayer game on the laptop, it checks the ports, says up and running, and the game begins. When I start the game on the workstation, it checks the ports, says up and running and then nothing happens. The game never starts. If I start the game on the laptop, I cannot see it from my workstation. I have disabled all virus software, spyware, and firewalls. Drivers are up to date. My computers see each other. DirectPlay works. WinXP with a Linksys WRT54G router. Even disabled the firewall in the router and forwarded all ports (although that should not affect a LAN game). What else can I check?
