Manually Configuring your Internet Connection

Unless your ISP assigns your configuration automatically via DHCP, you will need the

configuration parameters from your ISP. For example, if your router detected a PPPoE or PPPoA

service, you must provide a Login sequence in order to obtain an Internet connection from your

ISP. If your ISP requires a Static IP address, then you must provide the fixed addresses for Static

IP. The types of data you will need are highlighted in

Table 2-1

by connection method, and

explained in more detail below.

The information required by each of the connection types is described in the following table.

To configure your Internet connection:

1.

Enter your ISP Login information. Select the

Does Your Internet Connection require a

Login?

option based on the type of account your have with your ISP. If you need to enter login

information every time you connect to the Internet, select

Yes

. Otherwise, select

No

.

If your connection is PPTP or PPPoE, then you need to login. Choose Yes and enter:

–

Login.

This is often the name that you use in your e-mail address (for example, if your

main mail account is [email protected], enter jdoe).

Note:

When you enable remote management, we strongly advise that you change

your password. See

“Changing the Administrator Password” on page 7-6

for

the procedure on how to do this.

Password

. Enter the password you use to log in to your ISP.

•

Enter your

ISP Type

information:

–

Austria (PPTP

): If your ISP is Austria Telecom or any other ISP that uses PPTP to log in,

fill in the following fields:

•

Account Name

(also known as Host Name or System Name): Valid account name for

the PPTP connection. This is usually your email “ID” assigned by your ISP, the name

before the “@” symbol in your email address. Some ISPs require that you enter your

full email address here.

•

Domain Name:

Domain name or workgroup name assigned by your ISP, or your ISPs

domain name (optional).

•

Idle Timeout:

Select Keep Connected, to Keep the Connection Always On. To logout

after the connection is idle for a period of time, select Idle Time and enter the number

of minutes to wait before disconnecting in the Timeout field. This is useful if your ISP

charges you based on the amount of time you have logged in.

•

My IP Address

: IP address assigned by the ISP to make a connection with the ISP

server.

•

Server IP Address

: IP address of the PPTP server.

–

Other (PPPoE):

If you have installed log in software such as WinPoET or Enternet, then

your connection type is PPPoE. Select this option and configure the following fields:

•

Account Name

: Valid account name for the PPPoE connection

•

Domain Name

: Name of your ISPs domain or your domain name if your ISP has

assigned one (optional).

•

Idle Timeout

: Select Keep Connected, to keep the connection always on. To logout

after the connection is idle for a period of time, select Idle Time and enter the number

of minutes to wait before disconnecting, in the Timeout field.

2.

Enter your

Internet (IP) Address

.

–

Select the

Get dynamically from ISP

radio box if you have not been assigned any static

IP address. The ISP will automatically assign an IP address to the router using DHCP

network protocol.

–

If your ISP has assigned a fixed (static) IP address, select

Use Static IP Address

and fill

in the following fields:

•

IP Address

: Static IP address assigned to you. This will identify the router to your

ISP.

•

Gateway IP Address

: IP address of your ISP’s gateway. This is usually provided by

the ISP or your network administrator.

Domain Name Servers

(DNS). Domain name servers (DNS) convert Internet

names such as www.google.com, www.netgear.com, etc. to Internet addresses called IP

addresses.

Configuring Dynamic DNS (If Needed)

If your network has a permanently assigned (static or fixed) IP address, you can register a domain

name and have that name linked with your IP address by public Domain Name Servers (DNS).

However, if your Internet account uses a dynamically assigned IP address, you will not know in

advance what your IP address will be, and the address can change frequently. In this case, you can

use a commercial dynamic DNS service, which allows you to register an extension to its domain,

and resolves DNS requests for the resulting FQDN to your frequently-changing IP address.

For rollover mode, you will need a fully qualified domain name (FQDN) to implement features

such as exposed hosts and virtual private networks regardless of whether you have a fixed or

dynamic IP address.

Note:

At this point in the configuration process, you should now be connected to the

Internet.

Note:

If your ISP assigns a private WAN IP address such as 192.168.x.x or 10.x.x.x, the

dynamic DNS service will not work because private addresses will not be routed

on the Internet.

The gateway contains a client that can connect to a dynamic DNS service provider. To use this

feature, you must select a service provider and obtain an account with them. After you have

configured your account information in the gateway, whenever your ISP-assigned IP address

changes, your gateway will automatically contact your dynamic DNS service provider, log in to

your account, and register your new IP address.

To configure Dynamic DNS:

1.

Select

Network Configuration > Dynamic DNS

. The

Dynamic DNS

screen will display

with the default Dynamic DNS selected as None.

2.

Each DNS service provider—Dynamic DNS, DNS TZO or DNS Oray—requires its own

parameters (

Figure 2-9

). Select the tab for the DNS service provider you want to use and then

select the Yes radio box. Click

Apply.

3.

Access the Web site of the Dynamic DNS service provider you have chosen and register for an

account (for example, for dyndns.org, go to

).

4.

Complete entering the Dynamic DNS screen for the service you have chosen:

a.

Select the Use a dynamic DNS service check box of the name of your dynamic DNS

Service Provider.

b.

Enter the entire FQDN that your dynamic DNS service provider gave you,

(for example,

myName.dyndns.org

).

c.

Enter the User Name and Password (or key) for logging into your dynamic DNS account.

d.

If your dynamic DNS provider allows the use of wild cards in resolving your URL, you

may select the Use wild cards check box to activate this feature.

For example, the wildcard feature will cause

*.yourhost.dyndns.org

to be aliased to

the same IP address as

yourhost.dyndns.org

Configuring Your Time Zone

The VPN firewall uses the Network Time Protocol (NTP) to obtain the current time and date from

one of several Network Time Servers on the Internet. In order to localize the time for your log

entries, you must specify your Time Zone.

To specify your time zone:

1.

Select Administration > Time Zone from the menu. The Time Zone screen will display.

2.

From the

Date/Time

pull-down menu, select your local time zone. This setting will be used

for the blocking schedule and for time-stamping log entries.

3.

Automatically Adjust for Daylight Savings Time

. Check this box for enable daylight

savings time.

4.

Select an NTP Server.

•

The

Use Default NTP Servers

is selected by default. If this is enabled, then the RTC

(Real-Time Clock) is updated regularly by contacting a NETGEAR NTP Server on the

Internet.

Figure 2-10

Note:

If your region uses Daylight Savings Time, you must manually select Adjust

for Daylight Savings Time on the first day of Daylight Savings Time, and

deselect it at the end. Enabling Daylight Savings Time will add one hour to the

standard time.
