when i start limewire it says that i am disconnected. i am behind a firewall but still connect easily to things like realplayer radio stations. i checked my ip address and it doesn't match the one i've got in my TCP/IP settings. is this what's not allowing me to perform the search function and if so do i go ahead and change the settings even though i still recieve my mail and use the internet with the other (incorrect) IP settings?
