IPFW setup

[Mi Ki]

Hi,

I was wondering if is possible to setup on one single freeBSD box bridge
to one interface and NAT to another.

So I would have one ehthernet card connected to the Internet then two
secondary network cards one for internal network to access Internet and
another for single server that will have all ports available to the
Internet users. I would like to use different public IP addresses to
accomplish that.  Anyone can share some light? If this is not possible
is there another way to do it?

regards
Marek
