Open Vpn. Surfshark configuration

[Sasha]

Hello Sasha.
Since OpenVPN app does not have a killswitch option, is there any reliable external application which <<does the job>>?
Thanks in advance.

HI. All paid providers have a killswitch.

If you want to use it for free, try Windscribe, they have not only a kill switch, but also a firewall that blocks ALL communication outside the tunnel. You can also use TunnelBear. TunnelBear calls the kill switch "Vigilant". It blocks all unsecured traffic immediately when the connection is broken and unblocks it only when it is restored.
