Looking for an alternative to cloudflare tunnel (lemmy.today)

Hi, I moved this year to another city, because my internet provider didn't give me a dedicated ipv4 address I can't use a dyndns like duckdns. Another thing to mention is, that I have a dslite tunnel. So I can't set up dyndns...

So my recent setup is a truenas server sitting under my desk. This is connected via cloudflared to the cloudflare tunnel. There I have my services like seafile or nextcloud configured. They are all pointing to a traefik instance that routes the traffic to the right container.

So to summarize what I have:

Truenas server
- multiple services
dslite tunnel
own domain
Cloudflare tunnel
v-server
- Nginx
- docker

To visualize the route the traffic is going

Internet - cloudflare tunnel - cloudfared docker - traefik docker - service (nextcloud) docker

So I want to setup something on my v-server that routes the traffic to my homeserver (truenas)

Internet - DNS (cloudflare) - v-server - (magic docker service on truenas) - traefik docker - service (nextcloud) docker

Does someone have an idea how to solve this?

Install Tailscale (1) on the VPS and (2) in a Docker container on TrueNAS. The Tailscale container #2 will replace the cloudflared container. Set the Tailscale #2 node as a subnet router exposing the Traefik container's netmask (you probably already know how to get networking going between two Docker containers).

What you'll end up with:

Internet -> DNS (your domain) -> VPS public IP (Tailscale node #1 ===> Tailscale node #2 in Docker on TrueNas) -> Traefik -> web apps on your TrueNAS

Tailscale is not bandwidth-limited like Cloudflare because the nodes only use Tailscale's servers for the initial rendez-vous (to get out of NAT), then you will use the direct bandwidth between the VPS and your home connection.

You will also be able to use other DNS services if you want, because you won't be forced to use Cloudflare's anymore.

This actually sounds insanely cool. Without having looked at their documentation, can you make a rough statement about the required hardware power for the VPS, especially if traffic may include bandwith heavy stuff like movie streaming or large data up/downloads?

In that case you should probably give up using your own domain and take the one from Tailscale because they would intermediate direct connections whenever possible.

The main limitation on the VPS would be bandwidth as well as total transfer, not so much processing power because their just be moving stuff through. They all come with limits.
