Issue Definition: According to the O365 SfB documentation, the 50k+ ports are optional:

Scope Agreement: This case will be considered resolved when we have updated the documentation to properly list the Hub's requirements or provided a timeline for when the Hub's SfB client will function like the desktop client in terms of port usage.
