8.1.7 DMZ Host
De-militarized Zone (DMZ
) hosting (also commonly referred to as “Exposed Host”) allows the
User
to specify the “default” recipient of WAN traffic that NAT is unable to translate to a known
local PC. This can also be described as a computer or small sub-network that sits between the
trusted internal private LAN, and the untrusted public Internet. The DMZ Host page is shown
below.
One PC can be configured to be the DMZ host. This setting is generally used for PCs using
“problem” applications that use random port numbers and do not function correctly with
specific port triggers or port forwarding. Once set up, the PC should be able to run the
application properly from behind the NAT firewall.
To set a PC as the DMZ Host, perform the following:
1)
Within the NAT Advanced screen, enter the computer IP address.
2)
Click "Apply" to activate the DMZ host.
To deactivate a DMZ Host PC:
1)
Within the NAT Advanced screen, clear the IP address field.
2)
Click on "Apply."
NOTE
If a specific PC is set as a DMZ Host, it is important to remember to set
this back to “0” when finished with the needed application, since this PC
will be exposed to the public Internet, though still protected from Denial of
Service (DoS) attacks via the Firewall.
