Cache XAUTH User Name and Password on Client - Allows the Global VPN Client
to cache the user name and password.

The user will be prompted for a username and password when the connection is
enabled, and also every time there is an IKE Phase 1 rekey.
• Single Session - Global VPN Client user prompted for username and password
each time the connection is enabled and will be valid until the connection is
disabled. The username and password is used through IKE Phase 1 rekey.

when connection is enabled. When prompted, the user will be given the option of
caching the username and password.

Virtual Adapter Settings - The use of the Virtual Adapter by the Global VPN Client
(GVC) is dependent upon a DHCP server, either the internal SonicOS or a specified
external DHCP server, to allocate addresses to the Virtual Adapter. In instances where
predictable addressing was a requirement, it is necessary to obtain the MAC address
of the Virtual Adapter, and to create a DHCP lease reservation. To reduce the
administrative burden of providing predictable Virtual Adapter addressing, you can
configure the GroupVPN to accept static addressing of the Virtual Adapter's IP
configuration. This feature requires the use of GVC version 3.0 or later.
• None - A Virtual Adapter will not be used by this GroupVPN connection.
