how: 2 NIC cards - 1 subnet: needed NIC1 on WAN though ...

thanks. I had to have 2 NIC cards
(although I didn't explain why - sorry),
because the WAN NIC is going thru a
wireless ethernet bridge which seems to reset each time
it sees a different MAC address.

If you're trying to setup your FreeBSD box as a "filtering bridge"
then actually, you only need one IP address which you assign to one of
your NICs, and leave the other one without an IP address. You can
actually make the whole thing work without assigning any IP numbers to
the NICs on the machine at all. (Although in that case, the box won't
be much use *except* as a filtering bridge).
