DMZ can be enabled or disabled.
WAN Ping Blocking
Computer hackers use what is known as “pinging” to find potential victims on
the Internet. By pinging a specific IP address and receiving a response from the
IP address, a hacker can determine that something of interest might be there.
The Modem can be set up so it will not respond to a ping request from WAN.
This heightens the level of security of your Modem.
To turn OFF the ping response, enable firewall at first, then uncheck “Respond
to ping on internet port” and click “Apply”. The Modem will not respond to any
ping from WAN.
HTTP Request Blocking
Computer hackers will also use HTTP request to attack your modem sometime,
also you can block the HTTP request from WAN by setting on modem.
To turn OFF the HTTP response, enable firewall at first, then uncheck
“Respond to HTTP on Internet Port” and click “Apply”. The Modem will not
respond to any HTTP ping.
