Virtual Server Settings
Use the Virtual Server function when you want different servers/clients in your
LAN to handle different service/Internet application type (e.g. Email, FTP, Web
server etc.) from the Internet. Computers use numbers called port numbers to
recognize a particular service/Internet application type. The Virtual Server
allows you to re-direct a particular service port number (from the Internet/WAN
Port) to a particular LAN private/internal IP address.
The Virtual server settings allow clients on the Internet to access certain
services on your LAN via the Internet. Use the Virtual Server function to access
a Web, FTP or a Telnet server etc. on your LAN via the Internet.
The DMZ function re-directs all packets (regardless of services) going to your
WAN IP address to a particular LAN client/server. If you would like to enable the
DMZ function, enter an IP address in the DMZ IP field. The value ‘0’ means
that the DMZ function is disabled.
The difference between the virtual server and the DMZ function is that the
virtual server re-directs a particular service/Internet application (e.g. FTP,
websites) to a particular LAN client/server, whereas DMZ re-directs all packets
(regardless of services) going to your WAN IP address to a particular LAN
client/server.
