Hi
Currently I’m running a few servers at my home and I own a domain. I’d like to access those servers from outside my network (right now that happens through a VPN) but I don’t know anything about A records and MX records and as I understand, that’s what’s needed to do this. So would there be a tutorial that explains this like I’m 5 years old?
No, the MX recourd is only for emails, and for the paths (like in your example), it’s handled by your server.
Also, the subdomains are
subdomain.yourdomain.com
.
