These fields

display only if

your ISP

requires a

login.

Encapsulation

Encapsulation is a method for enclosing multiple protocols. PPP

stands for Point-to-Point Protocol. The choices are:

• PPPoE (PPP over Ethernet)

• PPPoA (PPP over ATM)

Login

The login name provided by your ISP. This is often an email address.

Password

The password that you use to log in to your ISP.

Idle Timeout (In

minutes)

If you want to change the login time-out, enter a new value in

minutes. This determines how long the wireless modem router keeps

the Internet connection active after there is no Internet activity from

the LAN. Entering a value of 0 (zero) means never log out.

Internet IP

Address

•

Get Dynamically from ISP

. Your ISP uses DHCP to assign your IP

address. Your ISP automatically assigns these addresses.

•

Use Static IP Address

. Enter the IP address, IP subnet mask, and

the gateway IP address that your ISP assigned. The gateway is the

ISP’s wireless modem router to which your wireless modem router

will connect.

This field displays only

if no login is required.

Use IP Over ATM (IPoA)

. Your ISP uses classical IP addresses (RFC

1577). Enter the IP address, IP subnet mask, and gateway IP

addresses that your ISP assigned.

Domain Name Server (DNS) Address

The DNS server is used to look up site addresses based on their

names.

•

Get Automatically from ISP

. Your ISP uses DHCP to assign your

DNS servers. Your ISP automatically assigns this address.

•

Use These DNS Servers

. If you know that your ISP does not

automatically transmit DNS addresses to the wireless modem

router during login, select this option, and enter the IP address of

your ISP’s primary DNS server. If a secondary DNS server address

is available, enter it also.

ADSL Settings

ADSL settings of your wireless modem router work fine for most ISPs. However, some ISPs

use a specific multiplexing method and virtual circuit number for the virtual path identifier

(VPI) and virtual channel identifier (VCI).

Note:

You must use the Setup Wizard to select the correct country for the

default ADSL settings to work.

NAT (Network Address Translation)

NAT automatically assigns private IP addresses (10.1.1.x) to

LAN-connected devices.

•

Enable

. Usually NAT is enabled.

•

Disable

. This disables NAT, but leaves the firewall active. Disable

NAT only if you are sure you do not need it. When NAT is disabled,

only standard routing is performed by this router. Classical routing

lets you directly manage the IP addresses that the wireless modem

router uses. Classical routing should be selected only by

experienced users.

1

•

Disable firewall

. This disables the firewall in addition to disabling

NAT. With the firewall disabled, the protections usually provided to

your network are disabled.

These fields

display only if

no login is

required.

Router MAC Address

The Ethernet MAC address used by the wireless modem router on

the Internet port. Some ISPs register the MAC address of the

network interface card in your computer when your account is first

opened. They will then accept traffic only from the MAC address of

that computer. This feature allows your wireless modem router to use

your computer’s MAC address (this is also called cloning).

•

Use Default Address

. Use the default MAC address.

•

Use Computer MAC Address

. The wireless modem router will

capture and use the MAC address of the computer that you are

now using. You must be using the one computer that is allowed by

the ISP.

•

Use This MAC Address

. Enter the MAC address that you want to

use.

1. Disabling NAT reboots the wireless modem router and resets its configuration settings to the factory defaults.

Disable NAT only if you plan to set up the wireless modem router in a setting where you will be manually

administering the IP address space on the LAN side of the router.

Read

Chapter 9, Troubleshooting

. If problems persist, register your NETGEAR product and

contact NETGEAR technical support.

Note:

If you cannot connect to the wireless router, check the Internet

Protocol (TCP/IP) properties in the Network Connections section of

your PC Control Panel. They should be set to obtain

both

IP and

DNS server addresses automatically.

Change Password and Login Time-Out

For security reasons, the wireless modem router has its own user name and password that

default to

admin

and

password

. You can and should change this password to a secure

password that is easy to remember. The ideal password contains no dictionary words from

any language and is a mixture of uppercase and lowercase letters, numbers, and symbols. It

can be up to 30 characters.

2.

Enter the old password.

3.

Enter the new password twice.

4.

Change the login time-out to a value between 1 and 99 minutes if the default value of 5

minutes does not meet your needs.

period of inactivity to prevent someone else from accessing the router interface when you

step away.

5.

Click

Apply

to save your changes.

After changing the password, you are required to log in again to continue the

configuration. If you have backed up the wireless modem router settings previously, you

should do a new backup so that the saved settings file includes the new password. See

Back Up

on page 67 for information about backing up your network configuration.

Log Out Manually

The router interface provides a Logout command at the bottom of the router menus. Log out

when you expect to be away from your computer for a relatively long period of time.

Types of Logins

There are three separate types of logins that have different purposes. It is important that you

understand the difference so that you know which login to use when.

•

Router login

logs you in to the router interface. See

Log In to the N600 Modem Router

on page 24 for details about this login.
