4.6 Virtual Server

The Barricade’s NAT (Network Address Translation) firewall filters out unrecognized

packets to protect your Intranet, so all hosts behind the Barricade are invisible externally.

You can, if you desire, 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 PPTP VPN server at 192.168.123.6, 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 ... 16 17 18 19 20 21 22 23 24 25 26 ... 39 40
