- Network Address Translation (NAT)
Network Address Translation (NAT) allows multiple users at your local LAN site
to access the Internet using 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.
- 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
