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)

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

Thank you. It really was that simple

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.

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.

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

LetsEncrypt is a good option if you want to set it up yourself. More work than cloudflare though.

[–] state_electrician@discuss.tchncs.de 1 points 3 hours ago

I am using Let's Encrypt. Cloudflare is used for DNS validation.

Yup! This is what I do! Love it so much
