Hello, is there any easy way to set up .ovpn-file and launch connection to OpenVPN server, directing all connections from LAN to OpenVPN server? Yes, my country blocks access to sites like github.com. Content of ovpn-key is at http://paste.org.ru/?cmxo2s. hAP mini, RouterOS 6.49.2 stable.

No, you have to convert it manually. But you won't get anywhere with this one, current RouterOS doesn't support some options (auth SHA512, tls-auth).
