Portal GUEST - Does not redirect after all authentications

TiUM — Thu, 07 Jan 2021 18:22:46 GMT

Hello,

I have a problem within portal GUEST on ISE. After all authentications the portal does not open on any means, and i get connect to the internet without any problems, but i want the portal to open after the browser is open.

Everything looks ok in ISE and in WLC, screenshoots added.

Can some one help me with this?

Hi @TiUM

You have to adjust your redirect ACL. On the WLC in the redirect ACL "permit" means "do not redirect", "deny" means "do redirect". Line 7 in your ACL matches all traffic and includes a permit -> no redirect. If you remove line 7 in your redirect ACL all traffic which is not matched by the first 6 lines would match the implicit deny and is therefore redirected.

Hi @martin.fischer

After I delete the rule 7 it works fine, the next problem is after I do the login with credencials and obtain access granted nothing works. I can't browse to the internet.

I tested with Hotspot Portal where I only have to click on the button to accept and can pass from there... Says you are connected but no internet access =/

Hi @TiUM

Hard to say with the information given but make sure that the ordering of your policies is correct.
