BasRuiter: Tried everything exactly as described. Updated the registry with your script - took the value from the expert setting in Limewire (firewall: manual port forwarding) - update was successfully, tried Limewire and IE, did not work, rebooted the machine with the new settings, tried again but still no sucess!

Question: I only included the one firewall forwarding port mentioned in the Limewire expert (firewall) settings - not the inbound port at the top of the same page (different port), not the Windows NETBIOS File sharing ports (different ports), which are in McAfee currently excluded (different ports). Pls advise if I should retry including these in the registry update as well.
