This article will be more networking oriented. We’ll enable an OpenVPN server on MikroTik RouterOS, and we’ll do so on the router with the shortest of names, the MikroTik RB4011iGS+5HacQ2HnD-IN. It should work on other MikroTik routers as well. We’ll be using RouterOS console in this article, but you should be able to do this with Webfig or Winbox too. Generate CA and Certificates To use OpenVPN securely, we’ll need certificates.
