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?

    On DNS you need A record if you have ipv4 only or A and AAAA records if you have ipv4 and ipv6.

    You DNS outside you home servers? If you have dynamic IP at home you can’t host DNS on home server.

    You have only 1 IP? You need port forwarding on you home gateway to home servers if you use somerhing like SSH. If you want access to something web based you need proxy. NGINX for example.

    How it exactly work:

    • Somewhere someone write youdomain.com in browser.
    • Browser ask local dns: who is youdomain.com
    • local dns ask another dns, and another and in one iteration request go to you dns. Or maybe some of dns have cached answer. But imagine that not.
    • You dns send answer youdomain.com is 111.222.333.444 for example. That is A record.
    • DNS work stop on that.
    • Browser send request to 111.222.333.444 with HTTP header “Host: youdomain.com” and some path. / or /something maybe.
    • Some balancer should get request and send in to right server in you home network.

    UPD: don’t show to internet something risky interfaces. Proxmox web panel or something like that. This is a real bad idea. For that type of services VPN extremely greatest. Send you DNS to public without protection not a great idea too. Including pihole. I think you will get into some botnet already on the 3rd day of work.
