Example: Adding secure tunneling to an active-passive WAN optimization configuration
This example shows how to configure two FortiGate units for active-passive WAN optimization with secure tunneling. The same authentication group is added to both FortiGate units. The authentication group includes a password (or pre-shared key) and has Peer Acceptance set to Accept any Peer. An active policy is added to the client-side FortiGate unit and a passive policy to the server-side FortiGate unit. The active policy includes a profile that performs secure tunneling, optimizes HTTP traffic, and uses Transparent Mode and byte caching.
The authentication group is named Auth-Secure-Tunnel and the password for the pre-shared key is 2345678. The topology for this example is shown in Figure 333. This example includes web‑based manager configuration steps followed by equivalent CLI configuration steps. For information about secure tunneling, see “Secure tunneling”.
