Hello,  
i use Tor on my Win 2019 Server.  
I use a VPN and normally i can do a killswitch for any program by firewall, when i do this:

example firefox.exe  
my main network is private  
my vpn network is public

Now i do in the windows firewall and restrict the internet connection for firefox.exe when no public network is connected.

If vpn (public network) disconnect = firefox no connection.

But when i do this for tor.exe and also firefox.exe inside the tor folder, it does not work.

Which .exe or process is responsible for the internet connection in tor browser?  
which process should i have to restrict the connectoin, so tor is getting blocked?

hope you can help me

best regards

Tor.exe it the one which connects to the internet. Firefox connects to Tor.exe as a sock5h proxy. I don’t understand why it cannot be blocked by a firewall.

Which firewall? The standard one which is in Windows?

I don’t have a server to try it out.

**Edited 2024/06/06**  
OK, I tried this out on a vanilla Windows Pro and made a new rule applied in all profiles to block tor.exe in the desktop Tor Browser folder. This was using Windows Defender. Now a firewall is a firewall is a firewall and it would work with any.

Firefox starts and it just sits there waiting. I have logs. This is not really a kill switch.

To make a kill switch would require making some sort of script which would turn on/off this rule. I will leave this up to you to implement.

There it is. Now make that into a script.

Do it at the firewall rule place and not at the app rule place.
