Hi,

I need to blocked all ports for PC on router but I need use teamviewer. I allowed port 5938 on router, but teamveiwer showing No connection to internet and not showing ID.
What other ports I need allow to make it works?
The thing is that i must block internet on PC but need use only teamviewer. Using TW14
- not working when i allowed 80,443,5938
