http://www.limewire.com/english/content/firewalls.shtml gave me hope, but still cannot connect. I wonder my router and DSL modem are blocking the 127.0.0.1 ip. Perhaps the Limewire site (see above) works only if no router is controlling the connection. Its a single computer single modem system, but I seem to rememeber that router's act like firewalls. Do I have two firewalls? One is XP the other is Linksys router? What IP should I use?
