TESTING NEEDED: Multiple DHCP pools within a subnet
I posted this on the 2.1 board and didn't get any responses there, figured some people browsing this board might be interested also:
I recently committed initial support for multiple DHCP pools inside of a subnet, and you can set options specific to that pool to have the pools act differently.
Full details in the other thread here: http://forum.pfsense.org/index.php/topic,53716.0.html
It's currently in the 2.1 snapshots and I provided a patch against 2.0.x in that thread also.
