Description
Ping or Trace an IP
address
Ping—Use this to send a ping packet request to the specified IP address. This is
often used to test a connection. If the request times out (no reply is received), this
usually means the destination is unreachable. However, some network devices can
be configured not to respond to a ping. The ping results will be displayed in a new
screen; click Back to return to the Diagnostics screen.
Trace—Often called Trace Route, this will list all Routers between the source (this
device) and the destination IP address. The Trace Route results will be displayed in a
new screen; click Back to return to the Diagnostics screen.
Perform a DNS
Lookup
A DNS (Domain Name Server) converts the Internet name (e.g. www.netgear.com) to
an IP address. If you need the IP address of a Web, FTP, Mail or other Server on the
Internet, you can do a DNS lookup to find the IP address.
Display the Routing
Table
This operation will display the internal routing table. This information is used by
Technical Support and other staff who understand Routing Tables.

Configuration File Management
The configuration settings of the FVS124G VPN Firewall are stored within the firewall in a
configuration file. This file can be saved (backed up) to a user’s PC, retrieved (restored) from the
user’s PC, or cleared to factory default settings. You can also upgrade the firewall software with
the latest version from Netgear.
From the Main Menu of the browser interface, under the Management heading, select the Settings
Backup heading to bring up the menu shown below.
Figure 8-18:
Settings Backup menu
The options are described in the following sections.
Reboot the Router
Use this button to perform a remote reboot (restart). You can use this if the Router
seems to have become unstable or is not operating normally.
Note
: Rebooting will break any existing connections either to the Router (such as this
one) or through the Router (for example, LAN users accessing the Internet).
However, connections to the Internet will automatically be re-established when
possible.
Packet Trace
Click Packet Trace button to Select the interface and start the packet capture on that
interface.

Restoring and Backing Up the Configuration
IMPORTANT
! Once you start restoring settings or erasing the router, do NOT try to go online,
turn off the router, shutdown the computer or do anything else to the router until it finishes
restarting! This should only take a minute or so. When the Test light turns off, wait a few more
seconds before doing anything with the router.
The Restore and Backup options in the Settings Backup menu allow you to save and retrieve a file
containing your firewall’s configuration settings.
•
To save your settings, select the Backup tab. Click the Backup button. Your browser will
extract the configuration file from the firewall and will prompt you for a location on your PC
to store the file. You can give the file a meaningful name at this time, such as pacbell.cfg.
•
To restore your settings from a saved configuration file, enter the full path to the file on your
PC or click the Browse button to browse to the file. When you have located it, click the
Restore button to send the file to the firewall. The firewall will then reboot automatically.
An Alert page appears showing the status of restore operation.You need to manually restart the
router to make the restored settings effective.
IMPORTANT
! Do not try to go online, turn off the router, shutdown the computer or do
anything else to the router until it finishes restarting! When the Test light turns off, wait a few
more seconds before doing anything with the router.
Upgrading the Firewall Software
The routing software of the FVS124G VPN Firewall is stored in FLASH memory, and can be
upgraded as new software is released by NETGEAR. Upgrade files can be downloaded from
Netgear's website. If the upgrade file is compressed (.ZIP file), you must first extract the binary
(.TRX) file before sending it to the firewall. The upgrade file can be sent to the firewall using your
browser.
Note:
The Web browser used to upload new firmware into the FVS124G VPN Firewall must
support HTTP uploads. NETGEAR recommends using Microsoft Internet Explorer or Netscape
Navigator 3.0 or above.
From the Main Menu of the browser interface, under the Management heading, select the Router
Upgrade heading to display the menu shown below.

Router Upgrade menu
To upload new firmware:
1.
Download and unzip the new software file from NETGEAR.
2.
In the Router Upgrade menu, click the Browse button and browse to the location of the binary
image (.IMG) upgrade file
3.
Click Upload.
Note:
When uploading software to the FVS124G VPN Firewall, it is important not to interrupt
the Web browser by closing the window, clicking a link, or loading a new page. If the browser
is interrupted, it may corrupt the software. When the upload is complete, your firewall will
automatically restart. The upgrade process will typically take about one minute.
In some cases, you may need to reconfigure the firewall after upgrading.
Erasing the Configuration (Factory Defaults Reset)
It is sometimes desirable to restore the firewall to a known blank condition. This can be done by
using the Erase function, which will restore all factory settings. After an erase, the firewall's
password will be
password
, the LAN IP address will be 192.168.1.1, and the firewall's DHCP
client will be enabled.
•
To erase the configuration and reset the router to the original factory default settings, click the
Erase button (see
Figure 8-18
).
IMPORTANT
! Do not try to go online, turn off the router, shutdown the computer or do
anything else to the router until the router finishes restarting! When the Test light turns off,
wait a few more seconds before doing anything with the router.
You need to manually restart the router to make the default settings effective.After rebooting,
the router's password will be password, the LAN IP address will be 192.168.1.1 and the router
will act as a DHCP server on the LAN and act as a DHCP client to the Internet.
Be careful how you use this!
