WHAT PORTS DO I NEED TO OPEN TO ACCESS THE GAME?

To best access The Elder Scrolls Online, players should configure their routers to open the following outbound ports:
TCP / UDP Ports 24100 through 24131
TCP / UDP Ports 24500 through 24507
What I think would be useful is the ports required for the actual Launcher (PC =Bethesda.net_Launcher) used for the install and updates.
I have asked for these specifically for the Launcher but got no response except for a copy/ paste of the above.
I know they are different and the Launcher uses some ports for the newsfeed and other browser stuff. But it also opens ports to CDN sites like Akamai which I assume is for the install and download data. Here are the ones I can see currently when I first launch the Launcher (Mac but essentially the same thing) and it is idle.

The first two are probably newsfeed or browser related, not sure. But the others appear to be data related.
The port range even from this small sample is very different from the ESO client ranges.
If anyone from ZOS can get those details it may help with some of the Launcher issues and especially for those asking college tech etc. to open up port access.
