I have our website running on a 2000 computer and in a DMZ. We are using a soho firebox 700 that is forwarding web traffic to this dmz computer. for some reason when people request websites its causing to much traffic on the internal network and ourinternet wont work which makes no sense since the web server is in a DMZ. anyone heard of this?

This type of thing becomes a matter of the network design you have in place. Do you use switches or hubs? Is your web server multi-homed (2 network cards, each one on different networks with different IP addresses)? When you go to the webserver fromyour LAN, do you travel through the Firebox, or do you stay behind the firewall?

Basically, I would check out your network design. Somehow, the traffic for the webserver is hitting your internal LAN. I don't know the Soho Firebox myself, so maybeit does not filter traffic all that wall. Maybe it is broadcasting on your LAN as well as the DMZ port it has, and that traffic is what you are seeing internal.

There are some things to do. Run a sniffer on your internal LAN while requests to theweb server are occurring. See if the sniffer picks up packets meant for the DMZ on the LAN. If you are sure your network is segmented correctly, then this would point to a problem with the Firebox.

hope this helps
