Port fowarding is not working

[bluepickle151]

Hi I'm trying to setup a Minecraft server it works on Lan but for some reason it will not port forward. I feel like I have tried everything I have setup a port forwarding rule typed all different types of of ports. I have it set to 25565 to 25565 with both TCP/UDP enabled. I have Xfinity internet with a Arris surfboard Sb8200 modem and google Wi-Fi. I have contacted Arris directed and they said why could not help me because you port forward from my router.

I found this post which said I have to port ward to from my modem to my router and then to my server.
I Had a support session with google for 3 hours and they were not able to help. Please help me I have been trying to fix this for months. Oh by the way I am running my server on a raspberry pi 4 with 4 GB on Balena IO.
This is a link to what I followed to step the server.

This the error I am getting.

Also I have my modem connected to my router through an ethernet cable and then my router is connected to a switch which my pi is connected too.

I am wondering......you have the port range set to 25565-25565 trigger port is the same? To which IP are you sending the traffic 172.217.11.36? Is that the IP of the Raspberry Pi (server)?.

It got me thinking...you might be able to use GRC's Shields Up website to prob that exact port and see what happens.

Yes I have my port set to 25565-25565 and it is set to the ip of my raspberry pi.
Ok how would I port it on that website.

 

[Kshipper]

There is a feature there that lets the website probe a custom port. It is probably a few screens in past the basic tests that you should probably do too

Also I don't know if this helps but this is the error I get when trying to load into the server on a different WIFI.

I followed the links you provided and there are more links inside..one was this:

How to Port Forward - General Guide to Multiple Router Brands - Support | No-IP Knowledge Base

This guide is a port forwarding how to for the very beginner. Follow the steps outlined to find your default gateway for general port forwarding.

www.noip.com

It even shows you a port probing place you can go to verify the port is open. Lets do that.

Ok, will try it out.

Ok so I checked my external address with the 25565 port on a port checker which it said it was open but my server ip address with 25565 was not open so I asked my friend if he could join the server with my external address and he could!! I don't know why its working now maybe because I got rid of the port forwarding rule and ip reservation and then put it back but I did that before and it did nothing.

Ahh very good. That's why I had you do that. So that you could confirm that the port is open and the very next question would have been: "What is your external IP?". You can't give someone the internal IP address, when they are on the WAN side. Any IP address on 192.xxx, 172.xxx or 10.xxx is considered a 'non-routable address' which means the original engineering of all this doesn't allow those IP address ranges to be used on the Internet.

The router is designed to handle it all hence its name. It routes traffic from one network to another. Taking traffic from inside and changing it into packets that it can route and remembering where those packets came from internally.

The last bit of advice is that you will have to be aware of when your external IP changes, because it will change. Your ISP dynamically assigns those addresses from a pool of addresses and you might get a new one on the next power outage. No big deal just Google 'What is my IP' and you give that to your friend and you are back in business. If you want to avoid that hassle too that is what you use a service like Dynamic DNS outlined in your setup guide you linked.

Happy Minecrafting! =)

OK thank You this is the port checker I use Portchecker which shows you your external address also I think you forgot the link to the dynamic DNS
