Chapter 3

Protecting Your Network

This chapter describes how to use the basic firewall features of the Wireless Router to protect your

network.

Protecting Access to Your Wireless Router

For security reasons, the router has its own user name and password. Also, after a period of

inactivity for a set length of time, the administrator login automatically disconnects. When

prompted, enter

admin

for the router user name and

password

for the router password. You can

use procedures in the following sections to change the router password and the amount of time for

the administrator’s login time-out.

NETGEAR recommends that you change this password to a more secure password. The ideal

password should contain no dictionary words from any language, and should be a mixture of both

upper and lower case letters, numbers, and symbols. Your password can be up to 30 characters.

Changing the Built-In Password

1.

Log in to the router at its default LAN address of

with its default user name

of

admin

, default password of

password

, or using whatever password and LAN address you

have chosen for the router.

Note:

The user name and password are not the same as a user name or password you

might use to log in to your Internet connection.

Blocking Keywords, Sites, and Services

The router provides a variety of options for blocking Internet-based content and communications

services. With its content filtering feature, the router prevents objectionable content from reaching

your PCs. You can control access to Internet content by screening for keywords within Web

addresses. Content filtering options include:

•

Keyword blocking of HTTP traffic.

•

Outbound service blocking. Limits access from your LAN to Internet locations or services that

you specify as off-limits.

•

Denial of service (DoS) protection. Detects and thwarts denial of service (DoS) attacks such as

Ping of Death, SYN flood, LAND attack, and IP spoofing.

•

Blocking unwanted traffic from the Internet to your LAN.

The following section explains how to configure your

router to perform these functions.

Blocking Keywords and Sites

The

router

allows you to restrict access to Internet content based on Web addresses and Web

address keywords.

1.

Log in to the router at its default LAN address of

with its default user name

of

admin

, and default password of

password

, or using whatever password and LAN address

you have chosen for the router.

2.

On the main menu, select Block Sites to display the Block Sites screen:
