Skype for Business 2015 - FQDN Requirements Question / SSL

RFVDB used Ask the Experts™
I'm in the process of configuring my Reverse Proxy server for Skype for Business 2015.

I've read in many articles that one of the URLs to passthrough to the Skype Front End server is the "", and also elsewhere that you should have a "" FQDN and have these domains configured in your SSL Certificate.

I didn't see these URLs configurable in the Skype Topology Builder. Did I just not look deep enough? My External Web Service URL is just, could that domain apply for the "scheduler" and "mobility" services or do I need to specify each of these FQDNs in my SSL Certificate and as passthrough FQDNs in my Reverse Proxy? Or is enough? thanks!
