Description This article describes how to fix a problem where the HTTP Captive Portal redirection does not occur.
Scope FortiGate.
Solution

The HTTP authentication option must be enabled on the FortiGate to occur.

If this option is not enabled, the HTTP captive portal page (or perhaps a simpler disclaimer message) will not display and the user will not get authenticated access to the Internet (or whatever resources that the network provides access to).

 

This issue can be seen in both Wired and Wireless authenticated access configurations.

 

If it is seen that after enabling such a configuration the captive portal does not display, check that the following HTTP User Authentication option is enabled under 'User & Authentication'/'Authentication Settings'.

To do this in the CLI:

 

config user setting

(setting) set auth-type http

(setting) end

 

It should look as follows:

 

config user setting

(setting) show

config user setting
set auth-type http
set auth-cert "Fortinet_Factory"
end
