Backing Up Your Configuration
The configuration settings of the WNR3500 router are stored within the router in a configuration
file. You can back up (save) this file and retrieve it later. NETGEAR recommends that you save
your configuration file after you complete the configuration. If the router fails or becomes
corrupted, or an administrator password is lost, you can easily re-create your configuration by
restoring the configuration file.
For instructions on saving and restoring your configuration file, see “Managing the Configuration
File” on page 6-6.
Understanding Your Firewall
Your RangeMax Wireless-N Gigabit Router WNR3500 contains a true firewall to protect your
network from attacks and intrusions. A firewall is a device that protects one network from another
while allowing communication between the two. Using a process called Stateful Packet
Inspection, the firewall analyzes all inbound and outbound traffic to determine whether or not it
will be allowed to pass through.
By default, the firewall allows any outbound traffic and prohibits any inbound traffic except for
responses to your outbound traffic. However, you can modify the firewall’s rules to achieve the
following behavior:
•Blocking sites. Block access from your network to certain Web locations based on Web
addresses and Web address keywords. This feature is described in “Blocking Access to
Internet Sites” on page 3-1.
Tip: Before saving your configuration file, change the administrator password to the
default, password. Then change it again after you have saved the configuration file.
If you save the file with a new password, and then you later forget the new
password, you will have to reset the router back to the factory defaults and log in
using the default password of password. This means you will have to re-enter all the
router configuration settings.
