Changing the Administrator Password

The default password for the router’s Web Configuration Manager is

password

. NETGEAR

recommends that you change this password to a more secure password.

To change the Administrator password:

Note:

When configuring the router from a wireless computer whose MAC address is

not in the Trusted PC list, if you select Turn Access Control On, you will lose

your wireless connection when you click Apply. You must then access the

wireless router from a wired computer or from a wireless computer which is on

the access control list to make any further changes.

Warning:

MAC address filtering adds an obstacle against unwanted access to your

network by the general public. However, because your trusted MAC

addresses appear in your wireless transmissions, an intruder can read them

and impersonate them. Do not rely on MAC address filtering alone to secure

your network.

Tip:

Before changing the router password, use the router backup utility to save your

configuration settings with the default password of

password

. If you save the

settings with a new password, and 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.

“Managing the Configuration

File” on page 7-6

.

Understanding Your Firewall

Your RangeMax NEXT Wireless Router WNR834B 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 4-1

.

•

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 4-3

.

•

Scheduled blocking

Block sites and services according to a daily schedule. This feature is described in

“Scheduling

Blocking” on page 4-5

.

•

Allow inbound access to your server

To allow inbound access to resources on your local network (for example, a Web server or

remote desktop program), you can open the needed services by configuring port forwarding as

described in

“Allowing Inbound Connections To Your Network” on page 6-1

.

•

Allow certain games and applications to function properly

Some games and applications need to allow additional inbound traffic in order to function.

Port triggering can dynamically allow additional service connections, as described in

“Allowing Inbound Connections To Your Network” on page 6-1

. Another feature to solve

application conflicts with the firewall is Universal Plug and Play (UPnP), described in

“Using

Universal Plug and Play” on page 6-12

.
