Figure 4-28Virtual Server Table Screen
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 table. A virtual server is defined as a Service Port, and
all requests to this port will be redirected to the computer specified by the IP Address.
For example, if you have an FTP server (port 21) at 192.168.123.1and a Web server (port 80) at
192.168.123.2, then you need to specify the following virtual server-mapping table:
IP Address Server Port Virtual Port Application
192.168.123.1 21 80001 FTP
192.168.123.2 80 80002 HTTP
Notice: All the parameters must be set for the sake of regular execute. The Virtual Port controls
the corresponding mapping table; do not type the same virtual port number in this
column. The permitted virtual port numbers are from 80001 to 80002.4-2-14 Status Menu
