Then, when receiving a packet initiated from LAN, the Device will process it according to the
following cases:
1) A packet with IP address 192.168.16.65 and MAC address 00:15:c5:67:41:0f is allowed to
pass.
2) A packet with IP address 192.168.16.65 but with a different MAC address is dropped
immediately to prevent IP spoofing.
3) A packet with a different IP address but with MAC address 00:15:c5:67:41:0f is dropped
immediately to prevent IP spoofing.
4) A packet’s IP address and MAC address both are not defined in the
IP/MAC Binding List
:
(1) If
the
