13. Change the authentication method to
Use this string to protect the key exchange
(preshared key)
, and
enter the preshared key string, such as XYZ12345, as shown in Figure C-22. (This is a sample key string.
Yours should be a key that is unique but easy to remember.) Then click the
OK
button.
14. This new Preshared key will be displayed in Figure C-23. Click the
OK
button to continue.
15. From the Tunnel Setting tab, shown in Figure C-24, click the radio button for
The tunnel endpoint is
specified by this IP Address,
and enter the Windows 2000/XP computer’s IP Address.

Step 5: Create a Tunnel Through the Web-Based Utility
1.
Open your web browser, and enter
192.168.1.1
in the Address field. Press the
Ente
r key.
2.
When the User name and Password field appears, enter the default the user name and password
admin
.
Press the
Enter
key.
3.
From the Setup tab, click the
VPN
tab.
4.
From the VPN tab, shown in Figure C-28, select the tunnel you wish to create in the Select Tunnel Entry drop-
down box. Then click
Enabled
. Enter the name of the tunnel in the Tunnel Name field.
This is to allow you to
identify multiple tunnels and does not have to match the name used at the other end of the tunnel.
5.
Enter the IP Address and Subnet Mask of the local VPN Gateway in the Local Secure Group fields. To allow
access to the entire IP subnet, enter 0 for the last set of IP Addresses. (e.g. 192.168.1.0).
6.
Enter the IP Address and Subnet Mask of the VPN device at the other end of the tunnel (the remote VPN
Gateway or device with which you wish to communicate) in the Remote Security Gateway fields.
7.
Select fromtwo different types of encryption: DES or 3DES (3DES is recommended because it is more secure).
You may choose either of these, but it must be the same type of encryption that is being used by the VPN
device at the other end of the tunnel.
Or, you may choose not to encrypt by selecting Disable.
8.
Select from two types of authentication: MD5 and SHA (SHA is recommended because it is more secure).
As
with encryption, either of these may be selected, provided that the VPN device at the other end of the tunnel
is using the same type of authentication.
Or, both ends of the tunnel may choose to Disable authentication.
9.
Select the Key Management. Select Auto (IKE) and enter a series of numbers or letters in the Pre-shared Key
field. Check the box next to PFS (Perfect Forward Secrecy) to ensure that the initial key exchange and IKE
proposals are secure. You may use any combination of up to 24 numbers or letters in this field. No special
characters or spaces are allowed. In the Key Lifetime field, you may optionally select to have the key expire at
the end of a time period of your choosing.
Enter the number of seconds you’d like the key to be useful, or
leave it blank for the key to last indefinitely.
10. Click the
Save Settings
button to save these changes.
Your tunnel should now be established.

Appendix D: Finding the MAC Address and IP Address for Your Ethernet Adapter
Windows 98 or Me Instructions
Wireless-G ADSL Gateway
Appendix D: Finding the MAC Address and IP Address for Your
Ethernet Adapter
This section describes how to find the MAC address for your computer’s Ethernet adapter so you can use the MAC
filtering feature of the Gateway. You can also find the IP address of your computer’s Ethernet adapter. This IP
address is used for the Gateway’s filtering, forwarding, and/or DMZ features. Follow the steps in this appendix to
find the adapter’s MAC or IP address in Windows 98, Me, 2000, or XP.
Windows 98 or Me Instructions
1.
Click
Start
and
Run
. In the
Open
field, enter
winipcfg
. Then press the
Enter
key or the
OK
button.
2.
When the
IP Configuration
screen appears, select the Ethernet adapter you have connected to the Gateway
via a CAT 5 Ethernet network cable. See Figure E-1.
3.
Write down the Adapter Address as shown on your computer screen (see Figure E-2). This is the MAC address
for your Ethernet adapter and is shown in hexadecimal as a series of numbers and letters.
The MAC address/Adapter Address is what you will use for MAC filtering. The example in Figure D-2 shows
the Ethernet adapters’s MAC address as 00-00-00-00-00-00. Your computer will show something different.
The example in Figure E-3 shows the Ethernet adapter’s IP address as 192.168.1.100. Your computer may
show something different.

Note:
The MAC address is also called the Adapter Address.
