5.6 NAT
Network Address Translation (NAT) allows multiple users at your local site to access the Internet via a
single legal IP Address. 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. If NAT is disabled, all LAN side workstations must have legal IP addresses for Internet access. If
the router is used for routing application, not for Internet access, the NAT function can be disabled.
