Virtual Private Networking

Setting up a VPN tunnel connection requires that all settings and parameters on both sides of the 
VPN tunnel match or mirror each other precisely, which can be a daunting task. The VPN Wizard 
can assist in guiding you through the setup procedure by asking you a series of questions that will 
determine the IPSec keys and VPN policies it sets up. It also will set the parameters for the 
network connection: Security Association, traffic selectors, authentication algorithm, and 
encryption. The parameters used by the VPN wizard are based on the VPNC recommendations. 
You will be able to view the suggested VPNC recommendations on the VPN Wizard summary 
page before establishing a VPN tunnel connection.

To set up a Gateway VPN Tunnel using the VPN Wizard:

1. Select Gateway as your VPN tunnel connection. The wizard needs to know if you are 

planning to connect to a remote Gateway or setting up the connection for a remote client/PC to 
establish a secure connection to this device. 

2. Select a Connection Name. Enter an appropriate name for the connection. This name is not 

supplied to the remote VPN Endpoint. It is used to help you manage the VPN settings.

3. Enter a Pre-shared Key. The key must be entered both here and on the remote VPN Gateway, 

or the remote VPN Client. This key length should be minimum 8 characters and should not 
exceed 49 characters. This method does not require using a CA (Certificate Authority). 

4. Check the radio box for the WAN interface that will act as one end of this VPN tunnel: ADSL 

or WAN Ethernet.

5. Enter the Remote WAN IP Address or Internet Name of the gateway you want to connect 

to. 

•

Both the remote WAN address and your local WAN address are required. When choosing 
these addresses, follow the guidelines in 

 above.

•

The remote WAN IP address of the Gateway must be a public address or the Internet name 
of the Gateway. The Internet name is the Fully Qualified Domain Name (FQDN) as setup 
in a Dynamic DNS service. Both local and remote ends should be defined as either IP 
addresses or Internet Names (FQDN). A combination of IP address and Internet Name is 
not permissible.

6. Enter the Local WAN IP Address or Internet Name of your gateway.

The Local WAN IP address is used in the IKE negotiation phase. Automatically, the WAN IP or 
FQDN address assigned by your ISP may display. You can modify the WAN IP address to use your 
FQDN; required if the WAN Mode you selected is auto-rollover.
