Proxy based on MAC

[King, Michael]

I'd like to proxy user's off to a different RADIUS server based on
they're MAC address.

Currently, my NAS reports MAC address as  Calling-Station-Id =
"00-0D-93-EA-89-06"

I'd like any user that has a MAC starting with 00-0D-93 (and about 8
more MAC's) to be proxied off to another Radius server.

I've come up with a RegEX that matches Mac addresses.  (Least I think
it's close)

Correct me, cause I know I'm gonna get this wrong.  (First real try with
Regex) (I'm using 3 separart MAC's here)

DEFAULT Calling-Station-Id =~
"(00-0D-93-([0-9a-fA-F][0-9a-fA-F]-){1}([0-9a-fA-F][0-9a-fA-F]))|(00-03-
93-([0-9a-fA-F][0-9a-fA-F]-){1}([0-9a-fA-F][0-9a-fA-F]))|(00-05-02-([0-9
a-fA-F][0-9a-fA-F]-){1}([0-9a-fA-F][0-9a-fA-F]))"


But where does this go, and what else do I have to configure?
