•
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.
•
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.
•
If configuring your Ethernet port, 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 the ADSL
ISP Connection” on page 2-8
or
“Manually Configuring the Ethernet ISP Connection” on
page 2-9
.
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 192.168.1.1. You can erase
the current configuration and restore factory defaults in two ways:
•
Use the Erase function of the firewall (see
“Backup and Restore Settings” on page 6-25
).
•
Use the reset button on the rear panel of the firewall. Use this method for cases when the
administration password or IP address is not known.
To restore the factory default configuration settings without knowing the administration password
or IP address, you must use the reset button on the rear panel of the firewall.
1.
Press and hold the reset button until the Test LED turns on and begins to blink (about 10
seconds).
2.
Release the reset button and wait for the firewall to reboot.
