Hi, I know there's hunt groups, but can't I use a reg exp to indicate multiple MAC addresses in a Calling-Station-ID entry on the radcheck table, so users can use multiple computers? Here is what I have: user@domain Calling-Station-ID =~ 00-1c-b3-b1-3e-00|00-1c-b3-b1-3e-01|00-1c-b3-b1-3e-02 However, any MAC address is accepted...its not working like I think it should. Thanks! Eric
