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.

IP Subnet Mask
: This is usually provided by the ISP or your network administrator.
Gateway IP Address
: IP address of your ISP’s gateway. This is usually provided by
the ISP or your network administrator.
3.
Select your
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.
Select the
Get Automatically from ISP
radio box if you have not been assigned a static
DNS IP address.
If the
Use these DNS Servers
radio box
is selected, enter valid DNS server IP addresses
in the Primary DNS Server and Secondary DNS Server fields.
4.

to save your settings. Click
Test
to verify that the connection is active.
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.
