USG Series - IP MAC Binding

If you like to allow only specific devices connecting to your network, you can use IP-MAC binding.
With this feature, an IP-address will only be assigned to a pre-configured MAC address.

The pre-configuration is done with the static DHCP-assignment. 

- After you set up the static IPs you now easily can go to Configuration> Network> Interface>edit [your interface].
- On the very end of the configuration page you will find the static DHCP-Table.
Here you can tick the box for "Enable IP/MAC Binding

- The other option you have to enable IP/MAC Binding is to go to Configuration> Network> IP/MAC Binding and activate IP/MAC Binding for the interface you like:

- If now a PC connects to the network which is not listed in the static DHCP table, all traffic will be blocked.

Also if a PC connects to the network with its MAC listed in the static DHCP table but with another IP address configured (static IP address locally configured on the client), its traffic will also be blocked.
The IP address and the MAC must match to allow traffic

Congratulations, You now have successfully enabled IP/MAC Binding for your interface.
