Azure MFA–Publishing MFA Portals using Web Applicaion Proxy
The goal is to publish on premises Microsoft Multi Factor Authentication (MFA) server portals using Web Application Proxy Service (not Azure Application Proxy!) The Microsoft MFA has the following 3 portals:
1. User Portal – The User Portal section allows the administrator to install and configure the Multi-Factor Authentication User Portal.
2. Web Service SDK – The Web Service SDK section allows the administrator to install the Multi-Factor Authentication Web Service SDK.
3. Mobile App – The Mobile App section allows the administrator to configure settings for the Mobile App. There is also a Mobile App Web Service which needs to be installed to support mobile app activations.
At the end of the configuration, my goal is to provide a single direction URL for User Portal, Web Service SDK and Mobile App shown below:
