m0n0wall (1-1 for some clients and Outbound for different WISP sites that I operate).  Is there a
way to use the /27 block behind m0n0?  Set up some kind of a bridge using the /27 and not have it
NATed to clients behind m0n0?  I would like to give a client a public IP (from the /27) but still
monitor / filter traffic and access while not using NAT.

With a routed block, you probably want to put it off its own interface
on m0n0wall.  Give m0n0wall one of the IP's out of the /27 on that
interface, and use the rest for public IP'ed machines.

If you want to keep all the machines on the same interface, you should
be able to use 1:1 NAT to machines on the private network.
