Captive Portal no automatic redirect

[Dankau]

Hello,

our captive portal does not lead to the login page of the captive portal when connecting to the WLAN, the clients are allowed directly into the Internet without a login.

It somehow looks as if no CP is activated on the interface.
However, if I enter the IP address of the interface on the OPNsense with port 8000, the CP login page loads normally and I can log in there. A session can also be seen in the OPNsense.

We noticed the problem when we updated from version 21.7 to 22. Unfortunately, even a pure new installation with the transfer of the old configuration does not work. I also tested different version of 22, but all tests have the same results.

Deleting and recreating the entire configuration in the Captive Portal Administration also does not help.
We have already tested an "Allow any any" rule in the firewall rules and also directly entered ports 8000-10000 for the captive portal page.

The assigned interface in the Captive Portal is correct, the settings are correct, but somewhere has to be a misconfiguration.

Due to the size and complexity of our currently existing machines, we would like to avoid reconfiguring the machines from scratch -> We have around 70 different interfaces actively running with quite large sets of rules.

Unfortunately, we're a bit at the end of our rope there.
