What you are asking to do is not possible. You can't block via MAC on a WAN interface, because you are never seeing the actual MAC of the computer trying to connect to you. The connection has been run though so many different routers that the original source MAC is long since obfuscated.

If you did block the MAC that connections from a specific machine appear to be coming from, all you would do is block the next router up the line from you; which would potentially block you off from the Internet entirely.
