I have created a test network that requires authentication via a splash page however I would like user to still be able to access some things on the network without authenticating. I have allowed non-http traffic and setup a walled garden however this isn't working as tested via ping.
We use the walled garden feature and have a list of URLs that are allowed pre authentication. We do block all except the walled garden list. It does work for us, but we have domains listed more like *.meraki.com as opposed to what is shown above.
