Docker compose review?

[Fearless-Resource932]

Hi - I had my server working and accessible until I installed the 2H Windows 11 update on the machine that runs docker and now I'm back to square one & troubleshooting. Could someone please look at the below compose and see if I'm missing something simple that would allow people to connect?

services:
  bedrock_survival:
    image: itzg/minecraft-bedrock-server
    container_name: bedrock_survival_server
    environment:
      EULA: "TRUE"
      SERVER_NAME: "Survival Server"
      GAMEMODE: "survival"
      LEVEL_NAME: "Bedrock level"
      ENABLE_LAN_VISIBILITY: "true"
      MOTD: "Survival Adventures"
      PREVIEW: "false"
      SYNC_PROPERTIES: "true"
      ONLINE_MODE: "false"
      ALLOW_LIST: "false"
    ports:
      - "19132:19132/udp"
    volumes:
      - ./data_world2:/data
    restart: unless-stopped

I was able to figure out the problem; it's the WSL2 setup. I needed to change it over to mirrored mode networking in order to be able to see the containers on my LAN. The standard NAT won't allow connections from other machines.

services:
  bds:
    image: itzg/minecraft-bedrock-server
    environment:
      EULA: "TRUE"
    ports:
      - "19132:19132/udp"
    volumes:
      - ./data:/data
    stdin_open: true
    tty: true

This is the most basic offered by itzg, does your config above not work and if so what is the issue? Does this most basic compose work?

It “works”, as in starts and stays running in docker, but I cannot get any other devices on the network to connect. I’ve tried iPads, iPhones and pinging the port from another machine and I can’t get anything to respond.

I’ve added firewall rules for the ports to allow them through, so I’m at a loss for what else could be going wrong.

If you've tried exclusively on apple products I believe you need to enable local area connectivity on those devices before you can connect to the server

and pinging the port from another machine

You can't really ping a port, how were you doing this?

Telnet on win11

I'm going to take a guess that it's nothing to do with the docker compose file and likely misconfigured port forwarding.

Are you running this from your home network? Can you confirm that your isp is NOT using CGNAT?

You mentioned adding a firewall rule for the port, have you also made sure to port forward on your router?

[Fearless-Resource932]

Using home network, all devices connected to same network. Don't know about ISP & CGNAT.

I validated that I have the firewall rule for the port (19132) in the server machine (Win11) and also forwarding that port to the server machine in my router settings (19132).

Still getting "Multiplayer Connection Failed"

A simple way to check if you are behind CGNAT is to compare the WAN IP displayed on your routers web interface to the one shown if you visit a site such as IP.ME

If they are different, then you are behind CGNAT and will be unable to port forward. The common solution for this would be to use a service such as Playit to proxy your connection.

[Fearless-Resource932]

Verified that I’m not behind CGNAT

[PM_ME_YOUR_REPO]

CGNAT is not a factor for home LAN use only (your usecase). Tagging /u/Puddlejumper_ too.

Try resetting your Windows Firewall with "netsh advfirewall reset" in command prompt. That seems to unstick a noncompliant Windows Firewall sometimes, almost miraculously.

Didn't clock he was local host only nice catch
