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.
