Set Up MAC Address Filtering

MAC filtering allows you to define up to twenty Media Access Control (MAC) address filters to

prevent computers from sending outgoing TCP/UDP traffic to the WAN via their MAC

addresses. This is useful because the MAC address of a specific NIC card never changes, unlike

its IP address, which can be assigned via the DHCP server or hard-coded to various addresses

over time.

To configure MAC filters:

1.

From any SBG7580-AC Web Manager screen, click the

Wireless 2.4 GHz

or

Wireless 5 GHz

main

menu button

on the

SBG7580-AC Web Manager menu bar.

2.

Click

MAC ADDRESS CONTROL

from the

Wireless

submenu options list to display the MAC

Address Control screen.

from the MAC Address Filter List for the computer you want to allow or block.

4.

Enter the least significant byte of the starting IP address for the range you are setting up.

5.

Select the MAC Address Filter Type from the drop-down list:

o

None

: Allows all wireless devices to connect.

o

Whitelist

: Allows only listed wireless devices to connect.

o

Blacklist

: Allows only wireless devices that are not listed to connect .

6.

Click

Apply

.

7.

Repeat steps 3 thru 6 to add up to 20 MAC addresses.

8.

To delete a MAC address, click on the MAC address in the MAC Address list and then click

Delete.

Repeat for each MAC Address that you want to remove from the MAC Address list.

Note:

If you enable the firewall and set up custom port triggers, then you must configure the

firewall to allow traffic through those custom ports. See
