4.6 Virtual Server

The DI-704’s NAT firewall filters out unrecognized packets to protect your Intranet, so all

hosts behind the DI-704 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.

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 Enable

21 192.168.123.1 V

80 192.168.123.2 V

1723 192.168.123.6 V

1 2 ... 17 18 19 20 21 22 23 24 25 26 27 ... 34 35
