The Firewall function can protect router be attached by outside. The DMZ feature allows
you to specify one computer on your network to be placed outside of the firewall. This may
be necessary if the firewall is causing problems with an application such as a game or
video conferencing application. Use this feature on a temporary basis. The computer in
the DMZ is NOT protected from hacker attacks.
The DMZ(Demilitarized Zone) option lets you set a single computer on your network
outside of the router. If you have a computer that cannot run Internet application
successfully from behind the router, then you can place the computer into the DMZ for
unrestricted Internet access.
Please note: Putting a computer in DMZ may expose that computer to a variety of security
rules. Use of this option is only recommended as a last resort.
Respond to Ping on Internet Port
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 Gateway can be set up so it
will not respond to an ICMP ping from the outside. This heightens the level of security of
your Gateway.
To turn OFF the ping response, enable firewall at first, then uncheck
“Respond to ping on
internet p
ort” and click “Apply”. The Gateway will not respond to an ICMP ping.
Respond to HTTP on Internet Port
To turn OFF the HTTP response, uncheck
“Respond to HTTP on Internet Port” and click
“Apply”. The Gateway will not respond to an HTTP ping.
