I'm using BlackICE PC Protection 3.5 and it keeps reporting that it's blocking thousands of TCP port probes. I also see in the connections tab for limewire that I'm running as an Ultrapeer and I have many incoming hosts connected to me with the Leaf protocol.

Is my firewall (BlackICE) preventing users from connecting to me as clients? Should I tell my firewall to open 6346 (the port that Limewire options says it listens to). Is my firewall hindering Limewire from being an Ultrapeer?

I'm fairly certain this has nothing to do with Forcing IP, since that concerns to port forwarding through an IP masquerading machine.
