1 – 65535.

Destination IP address

IP range is to be blocked from going through the router, similarly set as the Source IP address above.

Destination Port [port or port : port]:

Traffic with the particular set destination port or port in the set

port range is to be blocked from going through the router. Default is set port from port range: 1 –

MAC Filtering is only effective on ATM PVCs configured in Bridged mode.

FORWARDED means that all MAC layer frames will be forwarded except those matching with any of

the specified rules in the following table.

specified rules in the following table.

By default, all MAC frames of the interface in Bridge Mode will be forwarded, you can check

Change checkbox and then press Change Policy to change the settings to the interface.

For example, from above, the interface atm0.1 is of bridge mode, and all the MAC layer frames will be

Blocking WAN PING

This feature is enabled to let your router not respond to any ping command when someone others

Time Restriction

A MAC (Media Access Control) address is the unique network hardware identifier for each PC on your

network’s interface (i.e. its Network Interface Card or Ethernet card). Using your router’s MAC Address

Filter function, you can configure the network to block specific machines from accessing your LAN

during the specified time.

This page adds time of day restriction to a special LAN device connected to the router. To Restrict

LAN device(s), please click Add button to add the device(s) from accessing internet under some set

time. To find out the MAC address of a window based PC, go to command window, and type

“ipconfig/all”.

having to specify a complete URL (e.g.to block any image called “advertisement.gif”). When enabled,

browser (HTTP) connection attempts using port 80 only.
