	Replying to my own post but heck live and learn...

	I think figured the best way to do this would be thru bridging, it gives my FreeBSD box an opportunityt to act as a firewall [don't need a router] for the office pc's with public ip's without the need for subnetting, and I think I would be able to also do natd on this box thru the outside interface.  This way internet can pass thru my firewall and reach the internal machines with public ip's, and when I run out of those I'll use private 10.x.x.x ip's and just do natd on them thru the same firewall/bridge....Does this setup sound sane/plausible?

	    internet

	    T1 Connection/Router

	    FreeBSD Firewall/Natd Bridge

	 Internal Lan with both public and private IP's

now to wait until Monday.......all this excitement and nothing to break.
