I am trying to setup an AD FS Proxy server on an Azure VM. The Primary AD FS Server(myadfsserver.cloudapp.net) is also deployed on an Azure VM(Server 2012 R2) in the same Virtual Network. I have spawned a proxy server in the same virtual network(myproxyserver.cloudapp.net) and have set it up as a Web Application Proxy(WAP). I want to use AD FS as the IdP using this proxy server. The AD FS Proxy can access the internal AD FS Server and am able to pull up the configuration from the internal AD FS Server. The appropriate Firewall rules are in place which allow for communication to the ADFS Server from the Proxy server.
I have added a Pass-through application in the Remote Access Management console in the Proxy server and added the backend and front end server url's as those of the internal AD FS server. When I try to access the following:
https://myproxyserver.cloudapp.net/adfs/ls/IdpInitiatedSignOn.aspx
I get a 'Webpage Not Available'. Is there any configuration I am missing? I have also ensured that the appropriate ACL's are in place.
