ZoneAlarm Firewall is on by default after you install ZoneAlarm software. You can turn it off and on, as necessary, for example, if you need to troubleshoot a connection.

To turn the Firewall on or off:

• Click in the ANTIVIRUS & FIREWALL panel of the ZoneAlarm software client.
• Move the Advanced Firewall ON/OFF slider to ON or OFF position, as necessary.

If the ZoneAlarm Firewall is on, the Advanced Firewall status line shows the message Blocks invasions and hacker activity, and the main status bar shows the message YOUR COMPUTER IS SECURE.

If the ZoneAlarm Firewall is off, the Advanced Firewall status line shows the warning Your firewall is not properly set, and the Fix Now button below. The main status bar shows the warning YOUR COMPUTER IS AT RISK, and the Fix Now! button next to it. Click one of the Fix Now! buttons to turn the Firewall on again.
