Have you verified your router "port forwarding" setup? Google How to set up port forwarding and there is a community link also. Google "Links 2003 port forwarding" and there's a lot of info regarding typical connection problems, and you may find your system being used with similar issues.
I have had this problem before and once the router ports were consistent with the game hosting issues were corrected.
It could also be your security system (firewall).
