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.

Virtual Server

Use the Virtual Server function when you want different servers/clients in your

LAN to handle different service/Internet application type (e.g. Email, FTP, Web

server etc.) from the Internet. Computers use numbers called port numbers to

recognize a particular service/Internet application type. The Virtual Server

allows you to re-direct a particular service port number (from the Internet/WAN

Port) to a particular LAN private IP address and its service port number.
