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 Service Port, and all requests to this port will be redirected to
the 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:
Service Port Server IP
21 192.168.123.1
80 192.168.123.2
1723 192.168.123.6
