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'd say to start with CF tunnels unless you need non-web based applications. Cloudflare tunnels require you to have a domain, though.

It has the added benefit that you have network monitoring, logging and some filtering for security that they do on top and you get to manage everything from their web interface.

be warned that the first time can be a bit confusing, but since it's done using their web interface it's easier than if you have a problem making wireguard work.

  1. Create a tunnel with a public hostname that will be the url to access that service. During the creation of the hostname specify you want it protected by L7 application firewall.
  2. Create a new self-hosted application in cloudflare application section and for starters use the default login email and in rules specify the list of emails that are allowed to login

you should now be able to access your application from anywhere.

Alternatively, if you have a DNS server in your home network you can add a private IP range to your tunnel. Let's say 192.168.0.0/24. Then when you connect with their pseudo-VPN (cloudflare warp or cloudflare ONE) you can directly use your home network's ip address from that device. If you tell your device to use a local DNS server that resolves your internal services, you'll be able to connect to them that way.
