4.3.3.3 MAC filtering settings
MAC filtering mode A common method of restricting WLAN network access
is to specify the Media Access Control (MAC) address of computers that
are allowed or denied access to your network. Every WLAN network
adapter is identified by a unique MAC address. The GlobeSurfer 3G sup-
ports MAC filtering based on either a list of denied or allowed comput-
ers. MAC filtering mode Allow specifies that the list of MAC addresses
is granted access to GlobeSurfer 3G. MAC filtering mode Deny specifies
that all computers except those in the list of MAC addresses are granted
access to GlobeSurfer 3G. Select Disable if you want to disable MAC fil-

the corresponding network adapters.
