Easy with the coffee.

Sorry for that misundersating

> ifconfig_fxp1="inet 192.168.0.1 netmask 255.255.255.0"
Did a thinking and found a possible error:
With TP cable connected to switch (same with hub):
xl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST>
media: autoselect (100baseTX <full-duplex>) status: active
^^^^^
The end of this line tells me that cable is connected.
If I pull the TP plug status will change to:
status: no carrier
So, between the second NAT server and the client inside this,
do you use the correct cables? (hub,switch indicate connected
network card?)
If you are using TP directly between the machines, remember
the cable needs to be a crossover.
That should solve the problem.
If it didn't, send the output of "ifconfig fxp1".
PeTe
(I'm covering all options, so if this you know you need
crossovers bear with me)
