Troubleshooting

–

Verify that the IP address for your firewall and your workstation are correct and that 
the addresses are on the same subnet.

After verifying that the LAN path works correctly, test the path from your PC to a remote device. 
From the Windows run menu, type:

PING -n 10 <IP address>

where <IP address> is the IP address of a remote device such as your ISP’s DNS server.

This section explains how to restore the factory default configuration settings, changing the 
firewall’s administration password to password and the IP address to 192.168.0.1. You can erase 
the current configuration and restore factory defaults in two ways:
