Virtual Private Networking Using IPSec Connections

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 will fail 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 help you 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 263) 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 UTM (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.
