ProSafe Dual WAN Gigabit Firewall with SSL & IPsec VPN FVS336G Reference Manual
Troubleshooting 10-7
v1.2, June 2008
• 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 VPN firewall to
“clone” or “spoof” the MAC address from the authorized PC. Refer to “Manually Configuring
the Internet Connection” on page 2-8.
Restoring the Default Configuration and Password
This section explains how to restore the factory default configuration settings, changing the VPN
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 VPN firewall (see “Configuration File Management” on page 8-
15).
• Use the reset button on the rear panel of the VPN 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 VPN firewall.
To restore the factory defaults:
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 VPN firewall to reboot.
Problems with Date and Time
The Administration | Time Zone menu displays the current date and time of day. The VPN firewall
uses the Network Time Protocol (NTP) to obtain the current time from one of several Network
Time Servers on the Internet. Each entry in the log is stamped with the date and time of day.
Problems with the date and time function can include:
• Date shown is January 1, 2000. Cause: The VPN firewall has not yet successfully reached a
Network Time Server. Check that your Internet access settings are configured correctly. If you
have just completed configuring the VPN firewall, wait at least five minutes and check the
date and time again.
