INSTALLATION GUIDE

APPENDIX B: RESETTING THE FIREWALL

It is possible to restore the default factory settings of a NETASQ Firewall. This operation will bring

the product into its initial state.

WARNING

Resetting a Firewall will completely remove the configuration made on the product. This

operation is irreversible, so don’t apply this procedure unless absolutely needed.

For a U30, U70, U120, U250 and U450

In order to reset a NETASQ U30, U70, U120, U250 or U450 Firewall, take a pointed object (a pen

for example). A small switch is located on the appliance’s front panel (between the USB port and

the VGA port) and is accessible through a hole in the hood. Keep the button pressed for about 15

seconds, until you hear a sound. The reset procedure will be automatically launched and after a

few minutes the initial settings will be recovered and the Firewall will reboot. This reboot takes

about 5 minutes, so do wait until the end of the procedure (you will hear a sound) before

reconnecting to the firewall. Caution: this operation will also reset the password.

For other products

For other products, resetting a NETASQ Firewall has to be done in console mode. Several

methods are possible to access the Firewall in console mode. The easiest one can be done with

the serial link. For this, use the serial cable provided with the Firewall in order to connect the

appliance and a PC through their serial port.

Start an application like HyperTerminal (accessible through the menu

Start\Programs\Accessories\Communication).

Choose a communication on the COM port and specify the following parameters:

Bits per second: 9600

Data bits: 8

Parity: None

Stop bit: 1

Traffic control: Hardware

The following invitation appears:

FreeBSD (U70XXA0Z089020) (ttyd0)

Indicate the “admin” login and the related password that you use to connect to the Firewall. Enter

the following command: defaultconfig -f and press Enter

FreeBSD (U70XXA0Z0899020) (ttyd0)

SSH Passphrase:

U70XXA0Z0899020>defaultconfig -f

A beep will sound and your Firewall will reboot. The Firewall is now restored to factory defaults.
