Single Tunnel Support for IPSec

Oracle SD-WAN Edge offers IPSec for securing signaling, media, and management traffic at the network layer by way of tunnel mode. Tunnel mode is used most often for connections between gateways, or between a host and a gateway. Tunnel mode creates a VPN-like path between the two gateways and encapsulates the entire original IP packet.

The following illustration shows one tunnel using one WAN link.

Note:

If the WAN link stops functioning, the tunnel stops transferring traffic.

This illustration shows the single connection tunnels described in the preceding text.
