2.6 NAT Network Address Translation (NAT) allows multiple users at your local site to access the Internet through a
single Public IP Address or multiple Public IP Addresses. NAT provides Firewall protection from hacker
attacks and has the flexibility to allow you to map Private IP Addresses to Public IP Addresses for key
services such as Websites and FTP.
Parameter Description
Virtual Server
You can have different services (e.g. email, FTP, Web etc.) going to different
service servers/clients in your LAN. The Virtual Server allows you to re-direct
a particular service port number (from the Internet/WAN Port) to a particular
LAN IP address and its service port number.
Special Applications Some applications require multiple connections, such as Internet games,
video conferencing, Internet telephony and others. In this section you can
configure the router to support these types of applications.
ALG Setting You can select special applications that need “Application Layer Gateway” to
support here.
UPnP Setting
It allows to Enable or Disable UPnP feature here. After you enable the UPnP
feature, all client systems that support UPnP, like Windows XP, can discover
this router automatically and access the Internet through this router without
any configuration. The NAT Traversal function provided by UPnP can let
applications that support UPnP smoothly connect to Internet sites without
any incompatibility problem due to the NAPT port translation.
Static Routing You can disable NAT function and setup the routing rules manually.
Click on one of the five NAT selections and proceed to the manual's relevant sub-section.
