One user ip is blocked, I like to block MAC. He is cheating and he is always changing his ip (with
some ip that is not blocked and is not used at the moment). I have add static arp entries for all
users with arp -s <IP> <MAC> but nothing was changed. User is changing his IP again and again.
Should I enable some option or something or maybe someone can tell me some hard way:) how to
implement this??

If he's smart enough to change his IP around to get around
restrictions, he'll be smart enough to change his MAC address too (and
might be doing that already).  That's not a good solution.

Sounds like it's time for a non-technical solution.  Depending on what
the environment is, the potential solutions will vary.

You'll never find a way to lock out a determined person via MAC and/or
IP address controls.
