 Subject:  Re: [m0n0wall] multiple subnets on single LAN interface?

Short Answer: No

Long Answer:
You have to route your packets if you do not participate in those 
subnets with a local interface.

Why not run the DHCP server with a range of IP addresses from the 
172.16.0.0/16 that you've reserved as the "DHCP RANGE" and that you will 
not and do not have current static assignments in?
