You have to have Administrator rights to be able to switch it of
If you have no other firewall running now but XP-firewall then there is no need to switch it of. Just add you TCP and UDP ports (listening and forwarded port in Limewire which BTW should be the same port for this to work)
In my case portnumber is 64048 (it's Danish but the tabs should be in the same places)
Press the exeptions tab
Tilføj port = Add port
