Purpose
The attached document explains how to configure WAN optimization to work on traffic passing through an IPSec VPN tunnel for FortiOS 5.0 and 5.2.
Note: The steps for configuring WAN optimization without IPSec are very similar. The only difference is that the WAN optimization rule will not point to an IPSec interface.
Scope
Expectations, Requirements
WAN optimization is available on FortiGate models with internal storage that also support SSL acceleration.
For more details on which models support WAN optimization see:
