Mit der OpenVPN Version 2.3.9 wurde eine neue Option hinzugefügt, um das Problem zu verhindern. Es wird dann nur noch der DNS Server des VPN Adapters angesprochen. Die neue Option „block-outside-dns“ kann sowohl in die Server Konfiguration eingetragen werden, damit es auf jedem Client angewendet wird als auch in die Client Konfiguration.

*Question*: Fixing registry with --block-outside-dns is simple, but what should we do with IPv6 in OpenVPN? Should we introduce an option to disable IPv6 DNS
OpenVPN block-outside-dns Jan 31, 2017 #openvpn #block-outside-dns. Recently I had issues with my VPN setup, specifically with my VPN over at premiumize.me. They seem to have added the block-outside-dns option to their OpenVPN setup. As that’s a Windows only question it doesn’t work on my OS X/Arch Linux machine and causes problems. The block-outside-dns command does stop all traffic because the DNS leak is plugged and there is no default gateway assigned on the VPN tunnel. I have tried everything I can think of to assign the gateway but nothing works. I have run the openvpn GUI as administrator, tried pushing various commands from the server, running those same various commands directly on the client; but everything results in no default gateway assigned. However, --block-outside-dns can be used by simply adding it to that config file, provided you use Windows Vista or newer (this does not work on Windows XP) Ensure you have a server push a suitable DNS server. For further help please post your log file at verb 4 See --log, --verb and --block-outside-dns in The Manual v23x This will cause the DNS entries for your VPN device to be used (and only while the VPN connection is active). You can set them according to the answer by @brunoqc. While you're at it, you should probably also add the openvpn option block-outside-dns, to ensure that DNS queries are not leaking.
