VPN Single-Armed Mode (stand-alone VPN gateway)

Note: This feature is available only on the PRO 100, 200, 300, 230, 330, and GX series.

VPN Single-Armed Mode allows you to deploy a SonicWALL with single port (WAN) utilized as a VPN tunnel termination point. Clear text traffic is routed to the single interface and the data is encapsulated to the appropriate IPSec gateway.
