Hello Mike, Well actually it's not a big problem, I got 100 GB a day passing through our gateway to our clients, as far i didn't find any problems for webservers wich are not NATed, as for clients who are in DMZ zone i sometimes get connection error, but it's 1 in 1000 connections. I run a box with the following configuration: Single PIII-866 MHZ RAM: 256 NIC: 2 Intel Gigabit ethernet cards (as far as i remember). Befor it I used a Firebox firewall and it really drived me nuts. Due to low productivity.
