Weird ultrapeer issue

I've got this weird issue with becoming an ultrapeer. I have a T3 and athlonXP so I can definitly handle the load but it seems when I become an ultrapeer I only gain a couple leaf nodes. I am behind a firewall so I used force ip, but I don't see how some could get through and others couldn't. The weird thing is this happens with gnucleus too, so I dunno. Anyone got any ideas?

Open port 6346 on your firewall to accept the Limewire traffic. Open it on both ends ... if you are unsure of how to do this, post your router information ... just brand ... on the board here and I'll post the directions.

Also, you may want to set your PC's IP in the DMZ if all you are doing is sharing with that particuar PC ... it works for me ... that sounds funny.
