Unknown port connection used by teamviewer service

Hi,

 

Running version 14.2.2558 on Ubuntu 18.04.

 

I noticed when I was connected to the machine, the teamviewer service was making a connection from ports that were not the usual 5938​ or 443 or 80.

 

In the attached pic you can see that there is a connection from port 47520. When there is a new connection, the port changes.

 

Is this normal? Thanks
