Okay I've been going back and forth on Google, forums, and AI chat trying to figure this out but seem to be having issues with UDP connectivity. I had a summary of what I've done so far below. Any help would be greatly appreciated. Minecraft Bedrock Server on Unraid Not Responding on UDP Ports (Host Mode) --- Environment Overview: Platform: Unraid running binhex-minecraftbedrockserver Docker container Networking Mode: Host mode Server Properties Config (Current): server-port=19135 (IPv4) server-portv6=19136 (IPv6) Port Forwarding: Configured on ISP-provided router to forward UDP ports 19135 and 19136 to Unraid. --- Steps Taken: 1. Initial Setup on Default Ports Initially tried to use the default Bedrock ports 19132 (IPv4) and 19133 (IPv6). Despite correct router forwarding and open iptables rules, the server was inaccessible externally and locally. Suspecting a conflict with the default ports, switched to custom ports 19135 and 19136. 2. Networking Configuration Verified Unraid has no restrictive firewall rules. Manually added iptables rules to allow UDP traffic on 19135 and 19136: iptables -A INPUT -p udp --dport 19135 -j ACCEPT iptables -A INPUT -p udp --dport 19136 -j ACCEPT Confirmed rules with: iptables -L -n | grep 19135 iptables -L -n | grep 19136 3. Server Bind Verification Checked if the Bedrock server is binding to the ports: netstat -tuln | grep 19135 netstat -tuln | grep 19136 Result: Both ports are listed as listening (udp for 19135, udp6 for 19136). 4. External Port Tests Verified router port forwarding by successfully connecting to a Java Minecraft server on a different port. Used online port check tools, which report 19135 and 19136 as timing out. 5. Local Testing Installed and ran Netcat inside the Unraid environment (via nicolaka/netshoot container) to test connectivity: nc -u -z 127.0.0.1 19135 Result: No response received on the ports. 6. Bedrock Server Logs Logs indicate the server starts successfully and binds to the correct ports: IPv4 supported, port: 19135 IPv6 supported, port: 19136 --- Issues Encountered: 1. Ports Timing Out: UDP ports 19135 and 19136 are not accessible externally, despite being forwarded on the router and open in iptables. 2. No Response Locally: Netcat tests show no response from the server on 19135. --- Remaining Questions: 1. Could there be a permissions issue or an internal misconfiguration in the Bedrock server container preventing UDP traffic handling? 2. Is there any additional Docker or Unraid configuration required for the server to respond to traffic on these ports, even in host mode? 3. Are there known issues with the Bedrock server when using non-default ports like 19135 and 19136? --- Request for Help: Looking for guidance on: 1. Debugging why the Bedrock server is not responding to UDP traffic, even though the setup appears correct. 2. Identifying any additional steps required to verify or resolve the issue. 3. Understanding if this is a known issue with the Bedrock server container or Unraid networking. Any insights or recommendations would be greatly appreciated!
