Domain instead of ip in Wireguard (lemmy.world)

Like the title says, I want to replace the IP address in a wireguard .conf file to be a domain instead.

I own a domain through cloudflare, so say I wanted to use vpn.example.org

What DNS record and info do I need to put into Cloudflare? (I am aware I'll need to update it if my ip changes)

It is that easy, like you said. And with Cloudflare and Caddy you can get TLS for your internal VPN hosts. I love that.

Note that most wireguard clients wont re-resolve when the dns entry changes and they will keep silently a failed tunnel so you would have to do some measure to periodically restart the tunnel.

Just an A record, you just need the domain query to resolve to your IP.

I do this on my home network which has a Dynamic IP. I wrote a script which I cron to check and update it if it changes https://github.com/MajesticTechie/CloudflareDynamicDNS

I do this with the dynamic dns plugin in OPNsense. It really is set-it-and-forget-it.
