We run sustained 30 MBits/sec (with spikes up to 80-100 Mbits/sec) on a pair
of Dell R200s with no problems.

This is 4.9-RELEASE and i386 (box had i386 4.4 on already, prior to upgrade
so I thought no need to install amd64 on it as it only has 2G of RAM on it.

In addition, that box happily can do up to 200k packets/sec as well.

I think a PE2850 with 4G of RAM for a firewall is overkill for 25 Megabits/s.
