9.2.3 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.
