Bit-Torrent Help with Dachstein LEAF Firewall

I am trying to tweak my Dachstein 2 floppy system to work best with
Bit-Torrent. I found this on the Bit-Torrent web site and am not sure how or
where to add:

Linux ipmasqadm

From Andy Haninger:

	ipmasqadm portfw -f (flushes all other rules.. optional)
	ipmasqadm portfw -a -P tcp -L [firewall IP] 6881 -R [client IP] 6881



I am not sure where to put the second rule and if this is the correct rule
or if I need another one? Any help would be appreciated very much.

I think the below is for a different version of the Linux firewall project:

Shorewall for Linux
From Mike808:

For systems that are using masquerading (NAT) and have something like the
following:

In /etc/shorewall/masq:

# All outgoing traffic from 192.168.1.X going out the eth0 interface
# will be NATed/masqueraded to appear to be originating from your external
# internet address A.B.C.D (i.e. SNAT outgoing packets)
eth0 192.168.1.0/24 A.B.C.D

And in /etc/shorewall/rules:

# Allow net zone traffic on the external interface to be destination NATed
(DNAT)
# to your computer's internal IP address (for example, 192.168.1.X)
# Allow BitTorrent traffic through - port 6969 is if you run a tracker
# And ports 6881 through 6889 are for incoming BitTorrent connections.
DNAT net loc:192.168.1.X tcp 6969
DNAT net loc:192.168.1.X tcp 6881:6889


Or this one:

Linux IPTables
From SDE:

iptables -t nat -I PREROUTING -p tcp --dport 6881:6889 -j DNAT
--to-destination <host>
... where <host> is the private or internal IP actually running the BT
client.
