cd>Jeg trorjeg formulerede mig forkert. Jeg har adgang til to net fra min computer: Et lokalt(LAN) og så internetet (Via USB) Jeg kan få ip adressen til internettet frem med Winsock men ikke ip adressen til mit LAN (har tjekket med ipconfig)
Er det ikke er spørsgmål om først at skifte Winsock\'ens port? Åbenbart er din InternetIP på WinSock\'ens default port. Efter at have hentet den, så kunne man måske skifte port, og køre WinSock1.LocalIP igen. Hvordan du finder den rigtige port har jeg ingen anelse om. ;-)
