1. MAC Filter Overview

Users can use MAC Filter as a method to restrict unauthorized stations from accessing the APs. ZyXEL's APs provide the capability for checking MAC address of the station before allowing it to connect to the network. This provides an additional layer of control layer in that only stations with registered MAC addresses can connect. This approach requires that the list of MAC addresses be configured.

2. ZyXEL MAC Filter Implementation

ZyXEL's MAC Filter Implementation allows users to define a list to allow or block association from STAs. The filter set allows users to input 12 entries in the list. If Allow Association is selected, all other STAs which are not on the list will be denied. Otherwise, if Deny Association is selected, all other STAs which are not on the list will be allowed for association. Users can choose either way to configure their filter rule.

3. Configure the WLAN MAC Filter

The MAC Filter related settings in ZyXEL APs are configured in menu 3.5.1, WLAN MAC Address Filter Configuration. Before you configure the MAC filter, you need to know the MAC address of the client first. If not knowing what your MAC address is, please enter a command "ipconfig /all" after DOS prompt to get the MAC (physical) address of your wireless client.

If you use SMT management, the MAC Address Filter configuration are as shown below.

Enter the MAC Addresses of wireless cards in the filter set to allow or deny association from these cards.
