I have applied the patch to IPTABLES which allows me to use it on a bridge. The iptables rules are working as I am using it for other things as well. If you do not have the patch applied, you get an error message when trying to run IPTABLES. The one filter rule I am using is as follows: tc filter add dev eth1 parent 1:2 protocol ip prio 1 handle 2 fw classid 1:2a I have the browsing match into the IPTABLES as it is a simpler one to check if it is working before I try the FTP connection tracking portion.
