Problems with redirect when link is HTTPS

(1/1)

thiago:
Good morning people,
I have a problem that captive portal only redirects to the authentication page when I try to access some http link, when it is an https link it does not redirect and the error.
I have read in some places that OPNSense has some limitations for running HTTPS redirection.
Any suggestion?
Thanks.

hbc:
HTTPS is generally a problem with captive portals, because the client requests a ssl secured webpage and you redirect to your portal with a certificate that will not match the expected webpage and you will get a ssl error.

Usually browsers and modern OSes request special HTTP URLs to detect captive portals.

You can also add special dhcp options to send the captive portal url to clients.
