OpenVPN Verbindungen können server-side erkannt werden


Junior Member

Recently some companies tries to block not individual users but entire IP addresses of VPN services, which is troublesome for both users and VPN services. Seems like they don’t have any automatic tools and block addresses manually. While I’m against any type of censorship, I was curious if it is possible to detect VPN or proxy users on the server side.

And the answer is yes, under certain conditions. And pretty accurate.
