cloudflare-ufw VS ufw-docker

Only allow tailscale traffic and cloudflare (you can install ufw and use the script here for cloudflare https://github.com/Paul-Reed/cloudflare-ufw )

On the server itself, I've installed UFW (Software firewall for linux). After installing it, I added a rule to only accept traffic on port 22 (ssh port) from local machines (192.168.1.0/24). Then I added a rule to only accept traffic on port 443 from cloudflare servers. I then generated myself some ssl certs for a new domain that I purchased. I then setup nginx to listen on port 443 for the domain that I bought using the certificates.

Is cloudflare-ufw (https://github.com/Paul-Reed/cloudflare-ufw) compatible when using Cloudflare Tunnels?

Instead you should restrict access to your server to their IPs yourself, perhaps using something like cloudflare-ufw.

And this script running in a cron job updates cloudflare ip's once per week:https://github.com/Paul-Reed/cloudflare-ufw

I am running ubuntu server 22.04 LTS and have fail2ban running on the host. This works great, no issues and IPs get banned for the rules I have in place. I am using UFW and have updated my after.rules for docker based on the recommendations here.

I use this without problems for Long time, https://github.com/chaifeng/ufw-docker

A solution is known and formed detailed here: https://github.com/chaifeng/ufw-docker

In any case, maybe try to compare the blocked port ranges with the ports you are using. Did you see this https://github.com/chaifeng/ufw-docker

https://github.com/chaifeng/ufw-docker For example.

ufw is nice, when you are on public networks. And very nice if you are playing with SSH-Server, Docker,.. on your notebook. Couse you write coding, I want to add this, if you use docker.

You can use use this for a more manual approach: https://github.com/chaifeng/ufw-docker

Sorry that's about the extent of my docker network knowledge. One other thing you can check though - are you running ufw on the host? If so you can try updating the config with ufw-docker.

Hi! I'm also new to the homelab category, but I have a bit of experience. I'm currently running Ubuntu 22.04, and the only problem what I had is docker containers not working with ufw. (Fix can be found here: https://github.com/chaifeng/ufw-docker) I've been running my stuff in Docker containers, and it worked pretty well for me. So if you are also new to this, I'd definetly recommend Ubuntu for its simplicity. (Also tons of already great tutorials on how to do literally anything)
