Root | SnapGear 2.0.1 guide

Select Quick Setup Wizard from the center of the page.

You will be prompted to log in. Enter the initial user name and password for your CyberGuard SG appliance:

User name:

root

Password:default

Note

If you are unable to connect to the Management Console at 192.168.0.1, or the initial username and password are not accepted, press the black Reset/Erase button on the CyberGuard SG appliance’s rear panel twice, wait 20 – 30 seconds, and try again. Pressing this button twice within 2 seconds returns the CyberGuard SG appliance to its factory default settings.

Enter and confirm a password for your CyberGuard SG appliance. This is the password for the user root, the main administrative user account on the CyberGuard SG appliance. It is therefore important that you choose a password that is hard to guess, and keep it safe.

The new password will take effect immediately, and you will be prompted to enter it when completing the next step.
