option is ignored in the PPP connection.

Administrators may modify the network settings to fit into existing networks. Some broadband service

subnet mask may differ from the default value 255.255.255.0 and service providers may assign some

specific network settings. Administrators should change the configuration according to what is given by

the service provider. The configuration may include "IP address", "Subnet Mask", "Default Router",

"Primary DNS" and "Secondary DNS". After changing network settings, be sure to leave "Reset

network at next boot" blank to skip installation when the system restarts. Otherwise the settings will be

erased.

VisualServer not only plays the role of server, it will also actively connect to servers outside to send out

messages or snapshots. When VisualServer starts, it will send out a system log to notify administrators.

Even in modem application, VisualServer will send out a connection log whenever it dials out to an ISP or

dialup server outside. If the administrator has setup some applications in either event mode or sequential

mode, VisualServer will send out snapshots once conditions are met. There are two methods to send files,

including e-mail and FTP. To ensure VisualServer sends out files correctly, administrators should set valid

"SMTP (mail) server" and "Recipient email address" as well as "Primary FTP Server", "Primary

FTP user name" and "Primary FTP password". “Return email address” is whom the mail will return

when the SMTP server rejects upon any failure. Some ISP may reject the mail if the address is invalid.

"Primary FTP remote folder" is the relative sub-folder in the remote FTP server.

In both methods, a "Secondary" server can be provided for backup connection. However the primary

server information should be entered first. If the primary server is not set, the related FTP or email will be

deactivated. Note that it may take time to connect to the secondary server after the first one fails and it

may affect some applications when conditions happen too often.

For security or network integration, administrators also can hide the server from the general HTTP port by

changing "HTTP port" to other than default 80. “Local FTP server port” can also be changed to other

than default 21. These ports of “Control Channel Port”, “Audio Channel Port” and “Video Channel

Port” which are used in media transmission can also be changed. Administrators should have enough

acknowledge before changing the default port.
