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

Testing the Path from Your PC to a Remote Device

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.
If the path is functioning correctly, replies as in the previous section are displayed. If you do not
receive replies:
• Check that your PC has the IP address of your firewall listed as the default gateway. If the IP
configuration of your PC is assigned by DHCP, this information will not be visible in your
PC’s Network Control Panel. Verify that the IP address of the firewall is listed as the default
gateway.
• Check to see that the network address of your PC (the portion of the IP address specified by
the netmask) is different from the network address of the remote device.
• Check that your cable or DSL modem is connected and functioning.
• If your ISP assigned a host name to your PC, enter that host name as the Account Name in the
Basic Settings menu.
• Your ISP could be rejecting the Ethernet MAC addresses of all but one of your PCs. Many
broadband ISPs restrict access by only allowing traffic from the MAC address of your
broadband modem, but some ISPs additionally restrict access to the MAC address of a single
PC connected to that modem. If this is the case, you must configure your firewall to “clone” or
“spoof” the MAC address from the authorized PC. Refer to “Manually Configuring your
Internet Connection” on page 2-7.
Restoring the Default Configuration and Password
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:
• Use the Revert to Factory default settings function of the firewall (see “Backing Up and
Restoring Settings” on page 7-5).
