I am wanting to add a splash page on one of the WLANs on the WLC (2504, 188.8.131.52) so that any time when users are signing on to the WiFi account it automatically redirect to this web page.
How best is the way to go about it?
Are you looking for just a web portal to sign in via guest access?
Under the security tab you can set the web authentication type to whatever page you want. You then under your layer 3 security of your SSID set it to "web policy" and choose authentication type you want. Typically people will set up authentication. The users will be authenticated under the local net users..
If you are looking for a redirect under the web login page you can set it up to redirect to an external source.
Or you can setup your own customer layer 3 security policy.
Are you using LWA or CWA?. I tried using the splash portal for redirect purposes and it did not work. I checked with TAC as they said do not use it.
Do you have an external server hosting the login page like ISE?
In the WLC the config is more or less the following:
