Note: It was reported by users and tested in the lab that version 7.2.6 the explicit proxy feature is disabled after reboot. The latest version 7.2.9 is not affected by the issue, explicit proxy is kept enabled after reboot as it is supposed to.
Effective from FortiOS v7.4.4 and later, explicit proxy features are no longer supported on FortiGate models with 2 GB RAM or less. For more information refer to this article.
