* Firewall Rules:
* pfSense Firewall: Ensure there are no firewall rules blocking incoming traffic on port 25565 (or the alternative port you're using).
* Local Firewall (ufw): While you've mentioned allowing the port, double-check the rule to ensure it's active and not conflicting with other settings.
* Port Forwarding Rule:
* Correct Destination IP: Verify that the "Redirect target IP" in the port forwarding rule points to the correct IP address of your Minecraft server.
* Protocol: Ensure the protocol is set to "TCP" for Minecraft.
* NAT Type: Check your ISP's NAT type. If it's strict NAT, port forwarding might be limited. Consider using a dynamic DNS service to obtain a static IP address.
* Network Configuration:
* IP Address Assignment: Ensure your Minecraft server has a static IP address within your local network.
* DHCP Leases: If using DHCP, check the DHCP lease for your Minecraft server to confirm its IP address hasn't changed.
Troubleshooting Steps:
* Verify Firewall Rules:
* Use the pfSense firewall logs to check for any blocked traffic on port 25565.
* Temporarily disable the firewall to isolate the issue. If the server becomes accessible, it's a firewall configuration problem.
* Test Port Forwarding:
* Use a port scanning tool like nmap or an online service like yougetsignal.com to check if port 25565 is open to the internet.
* Try accessing your server from a device outside your network.
* Check Network Configuration:
* Ping your Minecraft server from another device on your network to verify connectivity.
* Use a network diagnostic tool like traceroute to identify any network issues.
* Double-Check pfSense Configuration:
* Review the port forwarding rule for any typos or incorrect settings.
* Ensure that the NAT type is set to "Hybrid" or "NAT".
Additional Tips:
* Simplify the Setup: If possible, try a simpler setup, such as directly connecting your Minecraft server to the internet without a router. This can help isolate the issue.
* Consult the pfSense Community: The pfSense forums are a great resource for troubleshooting specific issues.
