5.4 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 allows you to
map private IP addresses to public IP addresses for key services, such as Web sites
and FTP. See Figure 5-18.
Table 5-15 describes the three NAT options.

You can have different services (for example, email,
FTP, Web, etc.) going to different service
servers/clients in your LAN. Address mapping allows
you to redirect a particular range of service port
numbers (from the Internet/WAN ports) to a
particular LAN IP address.
