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 
blocks of 32 IP's on two different subnets 209.17.xxx.xxx and 
216.18.10.xxx. Through one upstream provider...

What I would like to do is setup another box running BSD to act as a 
router/firewall kind of setup, and put all the machines on the protected 
side.

1. Can I somehow route both blocks of IP's through one machine? (2 
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 
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 
some other combination....

Any help would be appreciated....
