Item Activation Add Disable Source MAC address filter Description • Enable the source MAC filter by ticking the check box. • Press APPLY. • Now add the MAC Addresses from which the traffic should be dropped by clicking on ADD button. Each time one MAC Address entry can be added. MAC Address input should be entered with ':' separator. A valid MAC address will have 0 to 9 and A to F. Example: 00:e0:4c:69:0a:11 • Press APPLY. Now the traffic from the specified MAC addresses will be dropped. • To Disable Source MAC Filter, uncheck Source MAC Filter Enable check box. The list of the MAC Addresses can be kept in the database. • If the filter has to be avoided for a specific MAC address in the database, select the MAC address entry and click on Delete button. Port Triggering Port triggering allows some applications to function correctly that would otherwise be partially blocked by the firewall. Using this feature requires that you know the port numbers used by the Application. Once configured, operation is as follows: • A PC makes an outgoing connection using a port number defined in the Port Triggering table. • This Router records this connection, opens the additional INCOMING port or ports associated with this entry in the Port Triggering table, and associates them with the PC. • The remote system receives the PCs request and responds using the different port numbers that you have now opened. • This Router matches the response to the previous request, and forwards the response to the PC. Without Port Triggering, this response would be treated as a new connection request rather than a response. As such, it would be handled in accordance with the Port Forwarding rules. • Only 1 PC can use a Port Triggering application at any time. 6-28 Firewall Protection and Content Filtering 202-10085-01, March 2005
