Okay, when I go to http://www3.limewire.com:6346/, it says the test worked whether my firewall is turned on or off. When I go to http://www.grc.com/port_6346.htm , if my firewall is on, it returns "stealth," if my firewall is off it returns "closed" and no matter what port I go to it returns "closed." Something is weird about that, don't you think. Why would one test work and the other one fail. If the port is closed, then why does the first test say "Your test worked!"? And why does every port seem to be closed when my firewall is off. Is it my ISP?
