4.6 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
.
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

21
192.168.123.1

80
192.168.123.2
