I've set up a p133 as a firewall/gateway with 2 NIC's one for outside
traffic and one for internal traffic, the internal NIC is a 3com 905B
using the xl driver. It connects to another 905B over crossover cable to
my windows machine. When doing ftp transfers between the 2 internal boxes
performances is poor at the best, 202kB/sec. I've forced both nics to
100baseTX full-duplex but to no avail, the speed doesn't differ at all
from 10baseT/UTP half-duplex or any combination there of.

I'm running NAT with rl0 as the natd_interface.

Can anyone give me some hints as to what to look for?

System information:
ifconfig xl0
xl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet 192.168.3.2 netmask 0xffffff00 broadcast 192.168.3.255
        ether 00:10:5a:64:7b:5c

        supported media: autoselect 100baseTX <full-duplex> 100baseTX
<half-duplex> 100baseTX 10baseT/UTP <full-duplex> 10baseT/UTP

CHIPKO is the name I've given to the windows box to make sharity-light
work.
L22-212 is the name of the FreeBSD box
