4.6.1 Virtual Servers
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 Enable
21 192.168.123.1 V
80 192.168.123.2 V
1723 192.168.123.6 V
