Our company network is blocked to internet.

Only specific domains and IP's are allowed.

What need to allow to get Teamviewer client to work?

I found these (below) and put those, but still client cannot connect to Teamviewer "cloud".

Hello @k2x80w,

Welcome to the TeamViewer Community!

To use TeamViewer within your network, you must allow *@teamviewer.com through our ports.

You'll find which ports TeamViewer is using here: 📄 Ports used by TeamViewer

I hope this can help you!

Our Workstation firewall (WithSecure) do not allow * mark.

So *.teamviewer.com do not work.

Is there some ip range?

As explained in the article I shared:

The TeamViewer software makes connections to our master servers located around the world. These servers use a number of different IP address ranges, which are also frequently changing. As such, we are unable to provide a list of our server IPs.

Whitelisting *.teamviewer.com is the only solution here.
