4.5.1 Virtual Server

This product’s NAT firewall filters out unrecognized packets to protect your Intranet, so all hosts

behind this product are invisible to the outside world. If you wish, you can make some of them

accessible by enabling the Virtual Server Mapping.

A virtual server is defined as a Public Port, and all requests to this port will be redirected to the

Private Port of assigned computer specified by the Server IP. Virtual Server can work with

Scheduling Rules, and give user more flexibility on Access control. For Detail, please refer to

Scheduling Rule.

For example, if you have an FTP server (port 21) at 192.168.123.1, a Web server (port 80) at

192.168.123.2, and a VPN server at 192.168.123.6, then you need to specify the following virtual

server mapping table:
