how do enable these TCP ports for Bittorrent?

[Elton Woo]

 Allow incoming TCP 6881 - 6889 to join the torrent swarm.

I thought this might be a good time to try using / learn to use
Bittorrent. The red hat 9 rpm pacakage is already installed,
but I don't know if /how to enable the above ports.
If I go to security settings, I *know* that just saying TCP
is a trusted device will open all ports.

.... I guess this is something else I ought have learned to
do <*blush*> so feel free to rap me on the knuckles if
I'm asking a stupid / annoying question!
