trying to establish IFD on CRM2016 running in virtual network. DB for CRM on separate machine running SQL 2016. CRM has own machine called OrgCRMSvr. AD FS installed on domain controller server in network. Successfully set up INTERNAL HTTPS. SET UP CRM for IFD and configured AD FS for external. On host machine can successfully be challenged and logged into CRM (using "orgname.domain.com"). When trying to use iPhone over telephone carrier network (so as to go over the Internet) my Safari browser looks like it hit my Orgname.domain.com MS CRM web service and transferred over to my AD FS, adfs.domain.com, but throws 404 error - file or directory not found! I do my own DNS via DynDNS.org. I set up Orgname.Domain.Com as A record to point to my Internet I.P. address allocated by cable company to modem bridging to my router. I can successfully come through router using distinguished port to my Security Camera. So I know network is not my problem, as in blocked ports because of modem bridge state.
I fear there is something I forgot to add somewhere that is not in the TechNet installation resource.
If anyone has any ideas what I should do to correct this situation I welcome your direction.
