4.6.3 URL Blocking

URL Blocking will block LAN computers to connect to pre-defined Websites.

The major difference between “Domain filter” and “URL Blocking” is Domain filter require

user to input suffix (like .com or .org, etc), while URL Blocking require user to input a

keyword only. In other words, Domain filter can block specific website, while URL Blocking

can block hundreds of websites by simply a keyword.

URL Blocking Enable

Checked if you want to enable URL Blocking.

URL

If any part of the Website's URL matches the pre-defined word, the connection will be

blocked.

For example, you can use pre-defined word "sex" to block all websites if their URLs contain

pre-defined word "sex".

table indicates the MAC address and the expected IP address mapping of a client. There are

four columns in this table:

You can select a specific client in the “DHCP clients” Combobox, and then click on the “Copy

to” button to copy the MAC address of the client you select to the ID selected in the “ID”
