Depends on how much bandwidth.

Either that's not true, or there's a serious hardware issue there.  A
PII 266 is way more than enough hardware to fill a 5 Mb pipe, add as
little latency as any firewall, and be running at under 25%

I run a Soekris 4501, 486 133 MHz, 64 MB RAM, on my 6 Mb cable modem,
and with it floored with the ugliest load you could possibly throw at
a firewall (like a bunch of BitTorrent is always a good test, the pps
drags things to a crawl for some firewalls), my firewall runs at under
50% utilization.

By "utilization" above, I mean CPU, since CPU is almost always going
to be your first bottleneck on a firewall with a sub-500 MHz proc and
100 Mb NIC's.
