So I understand the obvious choice for why to create a reverse proxy for Plex.

In order to go to Plex.mydomain.com instead of the IP address.

So that's fine and dandy for not having to remember the IP address for your server.

However other than that why?

If it something for users to much easier connect to your server so that instead of going to plex.tv they go to Plex.mydomain.com?

I don't see how that is easier.

Is it for users to have their streams SSL encrypted?

Is it so you don't have to open 32400 in your firewall?

I can't seem to find a good reason to do this. Is there any performance increases?

please advise, is it worth the hassle to set up and if it is what are the Pros and Cons?
