See http://www.gnutellaforums.com/showth...threadid=53091 It appears OOL has started blocking or shaping ports up to 49000

The free ports are (49152 - 65535) & these are usually the very last for ISP's to block.

I sent a pm asking ELoXL for details about how he went about changing it whilst he was online but I didn't get a response so far. You'll find options to change port in Tools>Options>Advanced>Firewalls. You'd also need to change firewall setting if it uses a port setting. I asked ELoXL whether he has his LW setting to UPnP or manual port forwarding, etc.
