If you are suggesting you have multiple static IP's from your ISP, you will want to setup IP alias for each, then NAT them to the internal desired internal devices.

If they are getting the lease from isp, they are not behind the firewall. I'm suspecting your setup to be wrong.
Think (and do): isp <-> modem <-> pfSense <-> switch <-> clients

Read this a couple of times: http://www.cisco.com/networkers/nw04/presos/docs/SEC-1N20.pdf for the first 20 slides or so, it's a bit dated but hopefully explains a bit where a Firewall should be positioned etc.
and practice on your google-foo  ;) , lookup all things you don't fully understand….
