Backing Up Your Configuration
The configuration settings of the WNR1000v3 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 6-7.
Understanding Your Firewall
Your Wireless-N 150 Router Model WNR1000v3 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.
• Blocking services. Block the use of certain Internet services by specific computers on your
network. This feature is described in “Blocking Access to Internet Services” on page 3-3.
• Scheduled blocking. Block sites and services according to a daily schedule. This feature is
described in “Scheduling Blocking” on page 3-5.
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.
