SonicOS 5.8.1 Administrator Guide
• DHCP Lease - The Virtual Adapter will obtain its IP configuration from the DHCP
Server only, as configure in the VPN > DHCP over VPN page.
• DHCP Lease or Manual Configuration - When the GVC connects to the
SonicWALL, the policy from the SonicWALL instructs the GVC to use a Virtual
Adapter, but the DHCP messages are suppressed if the Virtual Adapter has been
manually configured. The configured value is recorded by the SonicWALL so that
it can proxy ARP for the manually assigned IP address. By design, there are
currently no limitations on IP address assignments for the Virtual Adapter. Only
duplicate static addresses are not permitted.

option is selected without selecting Set Default Route as this Gateway, then the
Internet traffic is blocked.

VPN tunnel. If this option is selected without Set Default Route as this Gateway,

Default Route as this Gateway enabled.

VPN connectivity.
