I've deployed CRM 2013 on Windows Server 2012 R2 using a separate ADFS Farm on Windows Server 2012 R2 and I have a Web Application Proxy cluster in the DMZ. You would think Microsoft would have a document somewhere on how to publish CRM through WAP, but alas, if it's out there, it's buried deep in the MS website and impossible to find.
Is there anybody out there who can give me instructions on how to accomplish this or point me to a document on how it's done? I don't know which URLs need to be published and what settings I need for each.
Hope this helps,
check this it may also help you when you proxy enabled
