To follow up on my issues with network speeds coming out of my firewall, I am
a bit embarrassed to admit that I had an old ISA 10 Mbps card connecting to
my LAN which was the culprit.
During the process of figuring things out, I removed my IPCOP configuration
and installed Etch + shorewall + faster NIC on the same box and am now seeing
roughly 15 Mbps connections like I am supposed to from my firewalled
I had to learn a bit about shorewall configuration and ensuring that my 2 NICS
were consistently labeled via udev (which fortunately happens automatically).
I am much more comfortable with my debian setup than messing around with
ipcop's web browser configuration.
