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 server" and "Secondary DNS server". After changing network settings, be sure to leave "Reset network at next boot" blank to skip next installation when the system restarts. Otherwise the settings will be erased.

Each NetworKam can be limited in bandwidth by administrators according to its priority and importance of location. "Bandwidth limit" is most useful to balance network utilization when multiple NetworKam are installed in the same network. It is more effective than changing image quality only and achieves better performance with adequate image size and quality. Keeping the value as zero means no limitation on bandwidth utilization.

For security or network integration, administrators also can hide the server from the general HTTP port by changing "HTTP port" to other than 80. “Local FTP server port” can also be changed to other than default port number 21. Administrators should have enough network knowledge to change the default port.

NetworKam not only plays the role of server, it will also actively connect to servers outside to send out messages or snapshots. When NetworKam starts, it will send out a system log to notify the administrator. Even in modem application, NetworKam 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, NetworKam will send out snapshots once conditions are met. There are two methods to send files, including e-mail and FTP. To ensure NetworKam 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". "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
