URL Blocking
URL Blocking
will block LAN computers to connect to pre-define 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

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".
Enable

MAC Address Control
MAC Address Control allows you to assign different access right for different users and to assign a
specific IP address to a certain MAC address.
MAC Address Control
Check “Enable” to enable the “MAC Address Control”. All of the settings in
this page will take effect only when “Enable” is checked.
Connection control
Check "Connection control" to enable the controlling of which wired and
wireless clients can connect to this device. If a client is denied to connect to this device, it means the
client can't access to the Internet either. Choose "allow" or "deny" to allow or deny the clients, whose
MAC addresses are not in the "Control table" (please see below), to connect to this device.
Association control
Check "Association control" to enable the controlling of which wireless client
can associate to the wireless LAN. If a client is denied to associate to the wireless LAN, it means the
client can't send or receive any data via this device. Choose "allow" or "deny" to allow or deny the
clients, whose MAC addresses are not in the "Control table", to associate to the wireless LAN.

In this page, we provide the following Combobox and button to help you to input the MAC address.
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” Combobox.
Previous page and Next Page
To make this setup page simple and clear, we have divided the
“Control table” into several pages. You can use these buttons to navigate to different pages.

In this scenario, there are three clients listed in the Control Table. Clients 1 and 2 are wireless, and
client 3 is wired.
1. The "MAC Address Control" function is enabled.
2."Connection control" is enabled, and all of the wired and wireless clients not listed in the "Control
table" are "allowed" to connect to this device.
3."Association control" is enabled, and all of the wireless clients not listed in the "Control table" are
"denied" to associate to the wireless LAN.
4. Clients 1 and 3 have fixed IP address either from the DHCP server of this device or manually
assigned:
ID 1 - "00-12-34-56-78-90" --> 192.168.12.100 ID 3 - "00-98-76-54-32-10" --> 192.168.12.101
Client 2 will obtain its IP address from the IP Address pool specified in the "DHCP Server" page or
can use a manually assigned static IP address.
If, for example, client 3 tries to use an IP address different from the address listed in the Control
table (192.168.12.101), it will be denied to connect to this device.
5. Clients 2 and 3 and other wired clients with a MAC address unspecified in the Control table are all
allowed to connect to this device. But client 1 is denied to connect to this device.
