I have been using BitTorrent quite a bit and I have seen pretty iffy
performance downloading FC5.
I am using the correct ports, my firewall handles it fine, and my ISP does
not block. Other downloads have not been a problem since the last router
upgrade.
Something else is going on here.

Also, if they are using a DLink hardware firewall/router, they need to
upgrade to the latest firmware revision. (And they will have to use XP to
do it. I could not get it to work otherwise.) The December 2005 update
fixes a bunch of problems with BitTorrent saturating the NAT.
