Access to all Portal / ARM interfaces only over HTTP/HTTPS
Reduce access / interfacing with ARM / Portal from a tenant perspective to only over HTTP / HTTPS.
This will allow for easier access to Azure Stack instances hosted outside of a tenant's corporate network by a user located within the corporate network (which typically restricts external access to HTTP/HTTPS ports for untrusted external internet addresses= via proxy)
