well, what do the firewall logs say? are they blocking any specific 
packets? How does the client "talk" to the server? How did you set the 
whole thing up? Is the server on your LAN with non-routable IP addresses 
and you forwarded the ports to the server from the WAN address?

The third hit on the search I described gives you this page, which talks 
about default port 1099:
