Maybe it is possible to edit an alias or something like this.I need this for blocking intruders because they know how to spoof mac adress and change ip adress.I know that the best solution is to buy managed switches  ;).</p>

<p dir="auto">Static ARP <br />
  Enable Static ARP entries<br />
  Note: Only the machines listed below will be able to communicate with the firewall on this NIC.</p>
<p dir="auto">However, then you have to add all known allowed MACs in the table below at this page.</p>
