Access home server from anywhere (lemmy.zip)

Hi, I know this topic has been talked about 70 thousand times but I’m still not sure.

I have home server on an intel NUC behind the ISP router. On it I have the standard arr apps, jellyfin, pi-hole etc etc. I would like to access them through a domain rather than an IP. So I set them up in docker, behind traefik, behind authelia and behind cloudflare. I am the only one that uses it.

Now, I’m worried about the security of it all. I’ve been searching here and there and I’ve read about cf tunnels, wireguard server, vps, vlan, OPNsense etc etc. I still don’t know what would be the most secure. Should I just stay with what I have?

EDIT: I'm not behind CGNAT

I use Tailscale with their DDNS feature that generates you a domain that resolves each of your Tailnet devices when connected. You can even run a command that generates an SSL cert for your given node and you can use that to further secure it with TLS in case you don’t want to deal with untrusted cert warnings.

This is especially useful for iPhones because they won’t keep your Tailscale VPN always on, but you can configure it so that requests to specific domains will activate and use your Tailscale VPN, which you just set to that generated one.

I was about to ask why you'd need DDNS for Tailscale, had no idea about iOS issues. Thanks!

Because even when you have static IPs it’s still nice to just use a host name, and to properly secure things with a certificate. It’s not really DDNS as much as it is plain old DNS, but it works without configuration on your part. Once you enable it, whatever the tailnet name of your device is, becomes ‘device name.yourdomain.ts.net’.
