Good Day Everyone!

I have been reading and reading, and still am a little confused on what =

path I should take.

I am the admin for a couple of smallish ISP's. We are currently running =

approximately 7 servers of various FreeBSD releases. We have 2 different=
=20
blocks of 32 IP's on two different subnets 209.17.xxx.xxx and=20
216.18.10.xxx. Through one upstream provider...

What I would like to do is setup another box running BSD to act as a=20=

router/firewall kind of setup, and put all the machines on the protected=
=20
side.

1. Can I somehow route both blocks of IP's through one machine? (2=20
different NIC cards installed). And still be able to use the public IPS =

on the inside... Web, Mail, DNS, SSL etc....

2. Can we still use the (public) IP's we have already setup on the=20
servers we are presently using? Or do I need to do some translation?

3. What setup would you recommend? Ipfw/natd? Bridge/ipfw? Or perhaps=20=

some other combination....

Any help would be appreciated....
