I was hoping somebody help me out. I recently switched to T-mibile from Sprint. While with Sprint, I setup my home Macbook for sceen sharing on my IOS devices and did the port forwarding with my router to allow me to VNC on an outside and, often times, Sprint cell network.
I just noticed today that this no longer worked on my cell phone and originally thought that Apple release messed something up or maybe something was messed up with a new version of VNC Viewer since when I'm on my home network everything works great but not when on T-mobile network.
However, today I decided to try it on my work wifi and the VNC connection to my Macbook worked great which means my setup at home is fine and so is the VNC Viewer app. It has to be something with T-mobile. Has anybody gotten this setup successfully so they can VNC with T-mobile network or does anybody know if they block it or something? This is quite a huge deal for me and likely a deal-breaker if T-mibile doesn't allow it.

Seems like you are getting an ipv6 address on the phone instead of ipv4. That might be the source of the trouble. Not sure if you can force ipv4 on the iPhone.
