Management via this SA: - If using the VPN policy to manage the SonicWALL security
appliance, select the management method, either HTTP or HTTPS.

Default Gateway - Allows the network administrator to specify the IP address of the
default network route for incoming IPsec packets for this VPN policy. Incoming packets
are decoded by the SonicWALL and compared to static routes configured in the
SonicWALL security appliance. Since packets can have any IP address destination, it
is impossible to configure enough static routes to handle the traffic. For packets
received via an IPsec tunnel, the SonicWALL looks up a route. If no route is found, the
security appliance checks for a Default Gateway. If a Default Gateway is detected, the
packet is routed through the gateway. Otherwise, the packet is dropped.
