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.
For example, if you have a local client PC that cannot run an Internet application (e.g.
Games) properly from behind the NAT firewall, then you can open the client up to
unrestricted two-way Internet access by defining a DMZ Host.
Parameter Description

DMZ Host IP Address
Enter a static IP Address to the DMZ Host. This IP Address
will be exposed to the Internet.
Virtual Server
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) to a particular LAN’s private IP
Address and its service port number.
