or access the Internet through the Wirele ss Router, that is, it will allow them if they Allow

IP/MAC binding feature can act on the packets initiated from the local computers to the
Wireless Router or outside computers. When receiving a packet initiated from LAN, the
Wireless Router will firstly determine the sender’s identity by comparing the packet with
the bindings in the IP/MAC Binding List, and then process the packet according to the
sender’s identity. The details are as follows:
1. If the sender is a legal user, the packet will be allowed to pass, and then be further
processed by other function modules.
2. If the sender is an illegal user, the packet will be dropped immediately to prevent IP
spoofing.
3. If the sender is an undefined user, there are two cases:
1) If the Allow Undefined LAN PCs check box is checked, the packet will be
allowed to pass, and then be further processed by other function modules.
2) Else, the packet will be dropped immediately.
