I am running Windows XP Pro on one machine and XP Home on the other. The only firewalls are the ones that come with XP SP2 and my router has a firewall as well. I opened the ports that the p2p clients use on my router and the Windows firewall, made no difference. Then I turned off all 3 firewalls, still, made no difference. I went to http://www3.limewire.com:6346/ and it said "Your Test Worked!". I have a cable internet connection. My cable modem is some generic no-name brand that came with the purchase of the high speed connection. My router is a Belkin 2.4Ghz 802.11b model# F5D6231-4 wireless router. I am connectiong from my home. My internet goes from my cable box to the cable modem, then from the modem to the router via cat5 ethernet cable, the signal is then sent via more cat5 to one computer from the router and sent wirelessly from the router to the other computer. Limewire 4.9 with JRE 5.0 Update 4. My ISP is Midco and they claim that they are not blocking/filtering ANY P2P programs (although I have suspected this all along). Any ideas?
