Destination Port: The port number or range used by LAN PCs in accessing external

network.

Note:

 Packets filtered in this function are transferred from LAN to WAN.

 If you are not familiar with all parameters to be configured, you can just configure

some of them and keep the left unchanged. And the filtering function can also be

implemented.

For example:

If you want to filter the PC at the IP address of 192.168.1.200 and make it unable to

access Internet. Then follow the instructions below:

First, click “ Advanced Setup” → “ Security” → “ IP Filtering” to enter the IP filtering

setup page and then click the “ Add” button to enter the page below to configure needed

parameters as below:

And then click the “ Apply/Save” button to save your setting.

Note:

 Principle of using “ IP Filter” function to prohibit BT download: when you use BT

software to download data, it needs to send request for connecting “ seed” server,

and when this request passes the router, the router’ s IP Filter function will hold it up

and ignore the request so that BT fails to connect the server and download will be

aborted.
