You don't indicate what you have tried that you think should work, but the browser does not send the MAC address with the request. About all you are going to see is an IP address, and probably not even the IP address of the client machine.

It may be possible to retrieve the MAC address with some javaScript and return it to the server in a hidden field, but it may not be possible due to security issues.
