Chapter 23 WAN Optimization, Web Cache, Explicit Proxy, and WCCP : Configuration examples : Example: Adding secure tunneling to an active-passive WAN optimization configuration : General configuration steps
  
General configuration steps
This section breaks down the configuration for this example into smaller procedures. For best results, follow the procedures in the order given:
1. Configure the client-side FortiGate unit:
• Add peers.
• Add an authentication group.
• Add an active WAN optimization policy.
2. Configure the server-side FortiGate unit.
• Add peers.
• Add the same authentication group
• Add a passive WAN optimization policy that applies application control.
• Add a WAN optimization tunnel policy.
Also note that if you perform any additional actions between procedures, your configuration may have different results.
