VPN Firewall and Network Management

v1.0, January 2010

When you click on the

SNMP System Info

link on the SNMP screen, the VPN firewall’s

identification information is displayed. This following identification information is available to the

SNMP Manager: system contact, system location, and system name.

To modify the SNMP identification information:

Click the

SNMP System Info

link on the SNMP screen. The SNMP SysConfiguration screen

will display.

Modify any of the information that you want the SNMP Manager to use. You can edit the

system contact, system location, and system name.

Click

Apply

to save your settings.

Managing the Configuration File

The configuration settings of the VPN firewall are stored within the VPN firewall in a

configuration file. This file can be saved (backed up) to a user’s PC, retrieved (restored) from the

user’s PC, or cleared to factory default settings.

Once you have installed the VPN firewall and have it working properly, you should back up a copy

of your settings to a file on your computer. If necessary, you can later restore the VPN firewall

settings from this file. The Settings Backup and Firmware Upgrade screen allows you to:

•

Back up and save a copy of your current settings.

•

Restore saved settings from the backed-up file.

•

Revert to the factory default settings.

•

Upgrade the VPN firewall firmware from a saved file on your hard disk to use a different

firmware version.
