# Firewall Access Control

Access Control lets you permit or deny specific WAN services to a specific computer. It works in conjunction with Schedule Rule, so that the access control rules are enforced only during the timeframes assigned to them. The default is to allow access to all WAN services by all computers.

You can also deny LAN access to any computer. For details, see MAC Filter.

The following items are on the Access Control screen:

- Enable Filtering Function: Click Yes to turn on the filtering function.
- Normal Filtering Table: Displays the IP address (or an IP address range) filtering table.

To add the computer to the filtering table:

1. To enable the access control settings, select Yes.
2. Click Add PC.
3. Enter the Client PC Description for the computer.
4. Complete the Client PC IP Address or an IP address range.
5. Select the appropriate settings for Client PC Service.

   Note that the Clear button applies only to the Port Range entries. To clear the port ranges and start over, click the Clear button.

6. Select the schedule rule that you want to apply to the access control settings.
7. Click OK.

   The router re-displays the Access Control page.

8. Repeat steps 2 —7 for each computer whose access you want to limit.
9. Click SAVE SETTINGS on the Access Control screen to save your settings.
