There is no need to configure the Security Policy as it is imported directly into the

of a large number of VPN clients and eliminates the need to configure each client
individually.
Group VPN may also be configured using digital certificates in the Security
Association settings. For more information on Group VPN configuration using digital
certificates, refer to the Authentication Service User's Guide on the SonicWALL
website: http://www.sonicwall.com/products/documentation.html.
