Thanks. Yes, I do have a router.
I have used
http://www.whatismyip.com and it tells me one address, and TWGS tells me one.
When I use the addy from that website, and try to start the server, I get this error :
Creating player listener...
Querying server IP addresses...
Binding player listener...
Error binding player listener (10049)
Closing player listener...
Cleaning up...
When I use the one that TWGS provides, I can connect to it, but nobody else. How do I find out the address my router is giving out?
