What version of LimeWire are you using . There is a very good chance your router has a hardware firewall in it But your description of you problem s pretty weak. But since you cant give the name and model of your router I don't know. Now go back and read what we need to help you.
If I wrote hey my LimeWire quit work everything else works what's wrong. Do you think anybody could answer that question.
