I'd like to open a TAC for captive portal configuration between a Cisco Catalyst WLC 9800CL version 17.3.5a and a Cisco ISE VM - version 3.1.0.518, the correct configuration occurs between the ISE and the WLC, as per the prints, but there is no navigation, even after authentication via captive portal. There is IP distribution, but there is no connection, we have already configured the ACL, allowing all traffic and even it does not connect. I would like to know if there is any version incompatibility or if there is something specific to this configuration. Apparently the WLC is not performing the routing due to some problem or configuration.
Raise a tac case is always a good idea. But, on the tests I did not see, on the prints, if the client is able to ping the gateway or something on the internet like 8.8.8.8 for example. So, it is not clear when you say no nagivation if you are facing a problem with connectivity or some DNS issue.
It is not expected that the WLC perform routing but , for guest access, I believe you might have interface vlan on the WLC and on the Core and the Core, as the gateway should send the traffic to your internet gateway.
