iptables port forwarding ... torrent tracker connectable

Port forwarding on a linux firewall so you seem connectable to an Internet torrent tracker.

# iptables -t nat -A PREROUTING -i eth3 -p tcp -d 1.2.3.4 --dport 51413 -j DNAT --to-destination 10.21.241.100:51413


where
1.2.3.4 is your Internet Address
and 10.21.241.10:51413 the socket used by your torrent client / client-daemon
