Figure 12-4 IP/MAC Binding List - Example Two
Note
1. If you have added the IP and MAC address pair of a trusted LAN host in the IP/MAC
Binding List, and later changed this host¶s IP address or MAC address, you must
also change the corresponding binding in the IP/MAC Binding List; otherwise the
host cannot access the Device and Internet. If the Allow Undefined LAN PCs
check
box is unselected, you must also add the IP and MAC address pair of any new host that
you add to your network, and make sure that
its Allow Internet Access check box is
selected; otherwise this new host cannot access the Device and Internet.
2. IP/MAC binding feature can only act on the packets initiated from the LAN hosts to
the Device or outside hosts, but cannot act on the packets within the LAN. If you
change a LAN host¶s IP address or MAC address, this LAN host will be unable to
access the Device and access the Internet through the Device, but it still can
communicate with the other LAN hosts, such as, it can browse Network
Neighborhood, use windows file and printer sharing services within the LAN, and so
on.
