Using Google OAuth Splash with a Walled Garden

By: Kamal Haidar


The Meraki sign-on Splash Page can be integrated with Google OAuth, requiring users to log in with credentials from a custom Google domain for network access. This Splash Page can be configured to block Internet access until sign-on is complete, but certain domains need to be added to the Walled garden ranges in order for OAuth to complete.

This article outlines how to allow Google OAuth to operate while still limiting pre-authentication Internet access.
