Access Control is a security feature that can help to prevent unauthorized
users from connecting to your wireless router.
This function allows you to define a list of network devices permitted or
denied to connect to the RG21S/RA21S. Devices are each identified by their
unique MAC address or IP address. Specific services can also be
allowed/denied for IP addresses.
Check/uncheck the “Enable MAC Filtering” and/or “Enable IP Filtering” box to
enable/disable MAC filtering and/or IP filtering.
