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.
