Changing between proxy and flow mode
By default proxy mode is enabled and you change to flow mode by changing the Inspection Mode on the
System Information dashboard widget. When you select Flow–based you are reminded that all proxy mode
profiles are converted to flow mode, removing any proxy settings. As well proxy-mode only features (for example, Web Application Profile) are removed from the GUI.
In addition, when you select Flow–based the Explicit Web Proxy and Explicit FTP Proxy features are removed from the GUI and the CLI. This includes Explicit Proxy firewall policies.
If required you can change back to proxy mode just as easily. As well, if your FortiGate has multiple VDOMs you can set the inspection mode independently for each VDOM.
