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?
