I've had a friends not be able to find me right after my dynamic ip gets reset. For example, Windows is set to cache dns names for around a day. So If your server ip changes, the old IP stays in the cache. Right-click on the network Icon and 'repair connection' will clear the cache. Probably not the problem, but good to know.
Also try the 'DMZ Host IP Address' option with your router and server - I've had problems with router ports and Linux before- DMZ opens everything to one PC in the LAN.
