3.2.1 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 the details, please refer to
Scheduling Rule .
