How to set up a firewall on Windows 10?

Question

Windows

But the laptop has an openvpn client that connects through port 443. I do the following:

• Deny all outgoing connections
  
• I create a rule and place it at the very top (that is, with a high priority) in which I allow outgoing traffic through port 443 via tcp. (through it, openpn also works)
  

As a result, the client does not even connect to the server. Why?! Is there a detailed instruction somewhere on how to wrap all traffic from a computer through openvpn and in case of a server crash or some kind of disconnects, so that the real ip would not be displayed? Or what am I doing wrong? I'm not even talking about tightening the rules in terms of prescribing from which ip the connection should be ... stupidly on one port does not even work.

Answer 1

There is a suspicion that you also blocked DNS? Openvpn by domain or ip ?
Did you open outgoing calls to your router?
