Cisco ISE web redirect not working

[Jason Weids]

Can anyone help with this. I have an open SSID doing MAC filtering to ISE with the following auth rules;

My devices is hitting correct rule for the unknown MAC but it is not redirecting me to the guest portal & is allowing me access in the associated VLAN assigned to the WebAuth policy.

Can you share your authz profile & ACL_WEBAUTH_REDIRECT configuration? Also, ensure that your host you are testing is reachable from the NIC being used for the guest portal prior to throwing down the redirect acl.
