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:
