This article describes how to fix the redirection when choosing the Webfilter Warning proceed option.
Scope
FortiGate.
Solution
When setting a FortiGuard local and remote category to Warning action on Webfilter. It is expected to show a warning page prompt with the Proceed and Go Back options. However, when selecting proceed, it will redirect to 8015 for HTTPS and 8008 for HTTP.
In this example, set the information technology with a warning action.
When we access www.fortinet.com, it shows a warning page as expected as it belongs to information technology which is set with Warning action.
When the proceed option is selected, the website is redirected to 8015 (when you access it using https).
To fix this problem, it is necessary to go to the firewall policy and set the inspection mode to the proxy: Technical Tip: Changing the inspection mode of the firewall.
