Using Google OAuth Splash with a Walled Garden

Overview

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 explains how to configure the Meraki sign-on Splash Page with Google OAuth while restricting pre-authentication Internet access. 

Prerequisites

• Firmware: MR28+ 
• Licensing: MR-ENT
