On Mikrotik OpenVPN Security

I use MikroTik Routerborads quite a lot on remote sites to establish a secure tunnel to connect to internal services remotely (for example for employee time clocks). I like using OpenVPN because it is simple to configure and supports both, L2 (tap) and L3 (tun) secure (encrypted) tunnels. MikroTik’s Routerboards on the other hand are quite cheap and are providing a neat “black box” appliance which can easily handed to people with no IT experience.
