Configuring the MAC filter list for Internal Wireless

Description
Wireless networking provides native MAC filtering capabilities that prevent wireless clients from authenticating and associating with the wireless security appliance. If you enforce MAC filtering on the WLAN, wireless clients must provide you with the MAC address of their wireless networking card. The SonicOS wireless MAC Filter List allows you to configure a list of clients that are allowed or denied access to your wireless network. Without MAC filtering, any wireless client can join your wireless network if they know the SSID and other security parameters, thus allowing them to “break into” your wireless network.
Resolution
Deployment Considerations :
Consider the following when deploying the MAC Filter List:
The MAC Filter List can be enabled on the Internal Wireless > MAC Filter List page if a virtual access point (VAP) group is not configured. If a VAP group is configured, the MAC Filter function needs to be enabled on the VAP object.
The virtual access point can configure its MAC Filter List or inherit global settings configured on the Internal Wireless > MAC Filter List page.
