ADVANCED > VIRTUAL SERVER
The firewall filters out unrecognized packets to protect your LAN (local area network);
so all computers networked with the DI-604 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 192.168.0.1, a Web server (port
80) at 192.168.0.2, and a VPN server at 192.168.0.6, then you need to specify the
following virtual server-mapping table:
Service Port
