DMZ
This screen allows you to configure the LAN PCs as a “DMZ”. The DMZ PC will receive the same IP address
as the WAN.
Figure 35. DDNS Screen Data - Dynamic DNS Screen
A DMZ allows a single computer on your LAN to expose ALL of its ports to the Internet. When doing this, the
exposed computer is no longer ‘behind’ the firewall.
The "DMZ" PC will receive all "Unknown" connections and data. This feature is normally used with applications
which do not usually work when behind a Firewall.
Note that the DMZ PC is effectively outside the Firewall, making it more vulnerable to attacks. For this reason,
you should only enable the DMZ feature when required.
Enable WAN IP
address
DMZ uses the default WAN IP address so no input is required. If known, the current
WAN IP address is displayed. If you are using a dynamic IP address and there is no
Internet connection, the WAN IP address is unknown.
PC For each DMZ, you must select a PC from the list. If the DMZ PC uses a fixed IP
address and is not in the list, you can add it using the “PC Database” option in the LAN
screen.
