Setup an OpenVPN server in Mikrotik @ Home

Looking to setup an OpenVPN server in Mikrotik at my home, so i could have access from my phone when mobile.
At home the Mikrotik has a pppoe-client that connects through it to the Internet and i enabled the IP>cloud domain name, due to the fact that i have a dynamic IP that changes every night.
I have seen loads of documentations and sites, but no idea how to implement the domain name in server and in client.
I would appreciate if someone could point me to the right direction, please.

You can choose the WAN interface-list instead of the public IP address (in the firewall). Your clients should connect to the cloud domain name. Not sure what OpenVPN is requiring in the configuration, but there are tons of samples and blogs about this topic.

Could someone point me to a tutorial and what to change, please?

And just use the Cloud DDNS you get from IP>Cloud in the OpenVPN client profile, that’s it.

Thanks @DarkNate. In the guide you provided, i have to substitute the example.com with my ip/cloud domain name, correct?
