IP/MAC Binding
Path: Network > LAN > IP/MAC Binding
Another available security measure is to only allow outbound traffic (from LAN to WAN) when the LAN node has
an IP address matching the MAC address bound to it. This is IP/MAC Binding, and by enforcing the gateway to
validate the source traffic’s IP address with the unique MAC Address of the configured LAN node, the administrator
can ensure traffic from that IP address is not spoofed. In the event of a violation (i.e. the traffic’s source IP address
doesn’t match up with the expected MAC address having the same IP address) the packets will be dropped and
can be logged for diagnosis.
