DMZ
The DMZ Host is a local computer exposed to the Internet. When setting a particular internal IP
address as the DMZ Host, all incoming packets will be checked by the Firewall and NAT algorithms
then passed to the DMZ host, when a packet received does not use a port number used by any other
Virtual Server entries.
DMZ setting for: indicate the related LAN PC and PVC ports which allow outside network to
connect in and communicate.
DMZ:
Disabled: As set in default setting, it disables the DMZ function.
Enabled: It activates your DMZ function.
DMZ Host IP Address: Give a static IP address to the DMZ Host when Enabled radio button is
checked. Be aware that this IP will be exposed to the WAN/Internet.
Select the SAVE button to apply your changes.
Virtual Server
In TCP/IP and UDP networks a port is a 16-bit number used to identify which application program
(usually a server) incoming connections should be delivered to. Some ports have numbers that are
pre-assigned to them by the IANA (the Internet Assigned Numbers Authority), and these are referred
to as "well-known ports". Servers follow the well-known port assignments so clients can locate them.
If you wish to run a server on your network that can be accessed from the WAN (i.e. from other
machines on the Internet that are outside your local network), or any application that can accept
incoming connections (e.g. Peer-to-peer/P2P software such as instant messaging applications and
P2P file-sharing applications) and are using NAT (Network Address Translation), then you will usually
need to configure your router to forward these incoming connection attempts using specific ports to the
PC on your network running the application. You will also need to use port forwarding if you want to
host an online game server.
