3.1.5 NAT Setup
3.1.5.1 Virtual Server
This device’s NAT firewall filters out unrecognized packets to protect your Intranet, so
all hosts behind this device 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 the details,
please refer to Scheduling Rule.
For example, if you have an FTP server (Service port 21) at 192.168.123.1, a Web
server1 (Service port 80) at 192.168.123.2, a Web server2 (Service Port 8080 and
Private port 80) at 192.168.123.3, and a VPN server at 192.168.123.6, then you
need to specify the following virtual server mapping table
Service Port Private Port Server IP Enable
21 192.168.123.1 V
80 192.168.123.2 V
8080 80 192.168.123.3 v
1723 192.168.123.6 V
Afterwards, click on “Save” to store your settings or click “Undo” to give up the
changes.
