11.1. NAT
Network Address Translation (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. Select Disable to disable the NAT function.
11.2. Port Mapping
Port Mapping allows you to re-direct a particular range of service port numbers (from
the Internet / WAN Port) to a particular LAN IP address. It helps you to host servers
behind the router NAT firewall.
