I have a firewall acting as an internet choke point, and I am seeing strange readings while trying to track bandwidth usage. I am using iptables extensively, and it seems that whenever iptables rules have been applied to an interface, the 'transmitted bytes' field does not increment in /proc/net/dev; the 'transmitted packets' field does increment though. I am using a Redhat 9 base of 2.4.20 and p-o-m on top of it. I have 3 4-port D-Link cards with the "sundance" driver installed. Any help would be appreciated, as my lame bandwidth graph is pretty hurting with just half the info!
