the IPSec VPN Connection Status screen in view:
Figure 134.
b.
Locate the policy in the table, and click the
Connect
table button. The IPSec VPN
connection becomes active.
Note:
When using FQDNs, if the Dynamic DNS service is slow to update
its servers when your DHCP WAN address changes, the VPN tunnel
fails because the FQDNs do not resolve to your new address. If you
have the option to configure the update interval, set it to an
appropriately short time.

Description
About VPN Wizard
This VPN tunnel will connect
to the following peers
Select the
VPN Client
radio button. The default remote FQDN (remote.com)
and the default local FQDN (local.com) display in the End Point Information
section of the screen.
Connection Name and Remote IP Type
What is the new Connection
Name?
Enter a descriptive name for the connection. This name is used to help you
to manage the VPN settings; the name is not supplied to the VPN client.
What is the pre-shared key?
Enter a pre-shared key. The key needs to be entered both here and on the
remote VPN gateway, or the remote VPN client. This key needs to have a
minimum length of 8 characters and cannot exceed 49 characters.

Click
Apply
to save your settings. The IPSec VPN policy is now added to the List of VPN
Policies table on the VPN Policies screen for IPv4. By default, the VPN policy is enabled.
This VPN tunnel will use the
following local WAN Interface
Select a WAN interface from the drop-down list to specify which local WAN
interface the VPN tunnel uses as the local endpoint.
Select the
Enable RollOver?
check box to enable VPN rollover, and select
a WAN interface from the drop-down list to the right of the check box to
specify the interface to which the VPN rollover should occur.
Note:
If the VPN firewall is configured to function in WAN auto-rollover
mode, you can use the VPN Wizard to configure VPN rollover and do not
need to configure this manually.
End Point Information
a
What is the Remote Identifier
Information?
When you select the Client radio button in the About VPN Wizard section of
the screen, the default remote FQDN (remote.com) is automatically entered.
Use the default remote FQDN, or enter another FQDN.
Note:
The remote ID on the VPN firewall is the local ID on the VPN client.
It might be less confusing to configure an FQDN such as client.com as the
remote ID on the VPN firewall and then enter client.com as the local ID on
the VPN client.
What is the Local Identifier
Information?
When you select the Client radio button in the About VPN Wizard section of
the screen, the default local FQDN (local.com) is automatically entered. Use
the default local FQDN, or enter another FQDN.
Note:
The local ID on the VPN firewall is the remote ID on the VPN client.
It might be less confusing to configure an FQDN such as router.com as the
local ID on the VPN firewall and then enter router.com as the remote ID on
the VPN client.
Secure Connection Remote Accessibility
What is the remote LAN IP
Address?
These fields are masked out for VPN client connections.
What is the remote LAN
Subnet Mask?
a. Both local and remote endpoints should be defined as either FQDNs or IP addresses. A combination of
an IP address and an FQDN is not supported.

Note:
When you are using FQDNs, if the Dynamic DNS service is slow to
update its servers when your DHCP WAN address changes, the
VPN tunnel fails because the FQDNs do not resolve to your new
address. If you have the option to configure the update interval, set it
to an appropriately short time.
4.
Optional step: Collect the information that you need to configure the VPN client. You can
print the following table to keep track of this information.
Use the NETGEAR VPN Client Wizard to Create a Secure Connection
The VPN client lets you set up the VPN connection manually (see
Manually Create a Secure
Connection Using the NETGEAR VPN Client
on page
220) or with the integrated
Configuration Wizard, which is the easier and preferred method. The Configuration Wizard
configures the default settings and provides basic interoperability so that the VPN client can
easily communicate with the VPN firewall (or third-party VPN devices). The Configuration
Wizard does not let you enter the local and remote IDs, so you need to manually enter this
information.
