 Virtual Server
Th is 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.
