Automatic Log Out

The Diva 2440 applies an automatic time-out to configuration sessions. When a configuration session is idle for more than the time-out value, the Diva 2440 automatically logs the user out. This reduces the risk of unauthorized persons taking advantage of a logged-in computer that has been left unattended. The time-out values cannot be configured and are set as follows:

If you are using the web interface, the time-out is 30 minutes.

If you are using Telnet, the time-out is 5 minutes.

Note: Changes that have not been saved are lost when the configuration session is terminated this way.

IP Filtering Security Level

The IP Filtering Security level is a built-in set of IP Filtering parameters that controls what is allowed through the Diva 2440 and onto your local network. The higher the security level, the less traffic allowed in, but this increases the chances of barring legitimate traffic.

1.From the main page, click ‘Security Settings’.

2.Choose a security level from the drop-down menu.

Note: For information on what each filtering level means, click on the ‘IP Filtering Security Level’ link to bring up the context sensitive help.

3.Click ‘Save’. The changes take effect immediately.

Network Address Translation

Network Address Translation (NAT) is used to ‘hide’ the local LAN from all external resources. The benefits of this are the ability for all connected computers to access the Internet using one Internet address and ISP account. NAT is always on. For more information on this topic, see Network Address Translation on page 52.
