BitTorrent Slow Using PCLinuxOS Internet Connection Sharing

If you are using BitTorrent and your downloads seems slow,
And you are using PCLinuxOS to share your internet connection
edit your /etc/shorewall/rules

and add the following rule...
DNAT net loc:ipaddress_of_machine_running_bittorrent tcp bittorrent_port


e.g.:
DNAT net loc:192.168.1.220 tcp 51234
