Unexpected iptables behavior in FC5

[Stanton Finley]

When trying to set up a port range for bittorrent using the commands (as
root):

/sbin/iptables -I INPUT -p tcp --destination-port 6881:6999 -j ACCEPT

and then:

/sbin/iptables-save > /etc/sysconfig/iptables

and then listing iptables with:

/sbin/iptables -L

I get:

ACCEPT     tcp  --  anywhere             anywhere            tcp
dpts:6881:iatp-normalpri

as part of the output. This does not seem to include the port range
6881:6999 but only port 6881 and I've never seen "iatp-normalpri" on
previous FC versions.

Does anyone have any insight as to what's going on here?
