FortiGate Next Generation Firewall utilizes purpose-built security processors and threat intelligence security services from FortiGuard labs to deliver top-rated protection and high performance, including encrypted traffic.
FortiGate as WCCP router: Intercepts HTTP and HTTPS sessions and forwards them to a web caching engine, caches web pages, and returns cached content to the web browser.
FortiGate as WCCP client: Accepts and forwards WCCP sessions and uses firewall policies to apply NAT, UTM, and more security features. Note that FortiGates may only operate as clients while in NAT mode (not in Transparent mode).
Note:
For a FortiGate acting as a WCCP Client, when the WCCP setting is enabled on a firewall policy to offload WCCP sessions to an external device, use the appropriate source and destination in that policy.
If the source and destination fields are 'all' on the firewall policy, the sessions will be offloaded to a WCP-compatible device, and if that device is not meant to accept all the traffic, the packets are simply dropped.
