My Limewire is set to use port 36818 by default. And yes I have recently installed the newest version of Limewire and Java and I have just updated my ZoneAlarm firewall. My computer has done this before you know. I spent 8 months last year without being able to connect to Limewire because aparently it had detected a firewall. Then one day it starts to work again all by itself. Now its stopped working again, but I thought this time I'm gonna try and sort it out myself and see what the problem is. Unfortunately I've run out of solutions to try.
