I did not clarify it. I am trying to connect to a third-party VPN server
with my PC as a client. I am asking about how to configure my PC so as
to connect to the server.

As long as my PC's firewall is stopped, VPN works OK. When I start the
firewall, VPN does not work (Firefox tries to connect to a web site but
it doesn't get a response).


OpenVPN client connects OK to VPN server, both with the firewall started
and stopped.
