2.4 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
2.4.1 Address Mapping
The Broadband router allows one or more Public IP
Address(es) to be mapped to a pool of local Private IP
Address(es). This feature is particular useful when you
have multiple global IPs and want to divide local users
into different groups.
2.4.2 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.
2.4.3 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.
