3.6 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 Web sites and FTP sites.
3.6.1 Port Forwarding
This allows you to re-direct a particular range of service port numbers (from the
Internet/WAN ports) to a particular LAN IP address. It also helps you host some
servers behind the router’s NAT firewall.
