Hello. I have the following problem. I host a minecraft server on my own machine
Hello. I have the following problem. I host a minecraft server on my own machine (CASAOS,Crafty controller), I connected a Cloudflare domain to the server, the problem is that anyone I share the domain with cannot enter the server. I can log in through the domain, not through a local connection. I also did a port forward through the LAN connection and it still doesn't work. I have removed the firewall on the router if you have any suggestions please…

For cloudflare, you need the proxy (cloud icon) disabled
!cgnat
We may have bad news for you :C
You may be under a CGNAT which is a method that ISP's use to conserve IPV4 IP's due to how limited they are now. What this means in plain terms is that your IP address is being shared with other people as your router goes to the ISP's router, by default this means port forwarding doesn't work.
We need to check if you are under a CGNAT and we got 2 options.
Option 1: commands
Depending on your OS, run the following command:
- Windows:
iex (Invoke-RestMethod -Uri "https://raw.githubusercontent.com/DominicTWHV/Is-It-CGNAT/refs/heads/main/windows.ps1")
- Linux: curl -s https://raw.githubusercontent.com/DominicTWHV/Is-It-CGNAT/refs/heads/main/linux.sh | bash
-# You should never run such things without reviewing and understanding the code
Option 2: manually
Open your router's configuration interface. Somewhere, you'll see something like 'external' or 'public' IP.
If your external IP is in one of the following ranges, you're basically screwed as long as port forwards go:
- 10.0.0.0/8
- 172.16.0.0/20
- 192.168.0.0/16
- 100.64.0.0/10
- any IPv6 address/range - This shouldn't be a problem, but Minecraft's IPv6 support is still rather quirky. You're at your own, but we're happy if you share your experience.
What do I do now?
You should ask your ISP for a public and IPv4 address (but this may cost you money).
NB: your internal IP should and most probably will be in one of the first three ranges, don't mix them upCheck this and verify you're not behind cgnat.
Everything is perfect for now thank you very much
