DMZ function.
Enabled: It activates your DMZ function.
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.
8.3 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.
The reason for this is that when using NAT, your publicly accessible IP address will
be used by and point to your router, which then needs to deliver all traffic to the
private IP addresses used by your PCs. Please see the WAN configuration section of
this manual for more information on NAT.
The device can be configured as a virtual server so that remote users accessing
services such as Web or FTP services via the public (WAN) IP address can be
automatically redirected to local servers in the LAN network. Depending on the
requested service (TCP/UDP port number), the device redirects the external service
request to the appropriate server within the LAN network.
