Publishing a server
If you want to publish a server to the Internet, first assign a fixed private IP address to the server to be published,
and register the IP address conversion table (Static IP masquerade). Then, configure a filter in the product to permit
access from outside the LAN. This allows packets of a specific protocol to be sent to the server in the LAN, and thus
the server can be accessed from the Internet.
Flow of settings
Following settings are required for publishing a server.
Router settings:
• Register the conversion table of protocol, port number
and the server IP address (Static IP masquerade, page 107).
• Change the settings to permit access (page 107).
Server settings:
• Set the server IP address.
• Change the settings of web, ftp, and other file server
software programs according to the services to be
published.
Note
When publishing the server to the outside of your LAN, be sure
to configure adequate security settings to maintain data integrity.
Inadequate security settings may cause PCs in the LAN to be
hacked, sniffed, intercepted, or destroyed, or their data to be lost.
Tip
You can use the netvolante DNS service to publish and operate a
server even when using a connection service that cannot assign
a fixed global IP address. Please refer to “Using the netvolante
DNS service” (page 104) for more information.
