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 which do not use a port number that is
being used by any other Virtual Server entries will first be checked by the Firewall and NAT
algorithms before they are passed to the DMZ host.
DMZ: indicate the related LAN PC and PVC ports which allow outside network to connect
in and communicate.
~ 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.

Virtual Server
TCP/IP and UDP is 16-bit number network ports that are used to identify which application
program (usually a server) each 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 that allow clients to locate them.
If you wish to run a server on your network that can be accessed from 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
