You can't split 2 identical networks, with identical
netmasks across 2 interfaces unless you are running some sort of
BRIDGE or transparent proxy support. Even then, if you have the
same IP's on both networks you will run into problems with routing
and ARP entries on the FreeBSD machine.
If you are looking to connect the 2 networks together, run a
different ip range on the (test) network, like the 10.0.0.0
or 192.168 network. If you are not connecting to the internet then
you will not need to run NATD, just make sure that the
gateway address of the machines on both sides are pointing to the
corresponding FreeBSD interface IP.
