Hello, good morning, evening or night depending on where are you from, i am here looking for some help, i have been trying to open a modded minecraft server so i can play with my friends, but i ran into an issue, as far as i have seen, i am not allowed to port forward, or there is something not letting the port, be ported forward itself, its quite annoying the fact that i already searched on whole internet and i still cannot seem to fix the issue.

My router is a Technicolor CGA4233TLV2

I have already sat a Static Ip to my computer, and i have already opened both TCP and UDP ports, i have tried with one TCP and one UDP at the same time, and with only one with the BOTH feature enabled, but still when i get into yougetsignal.com it still seems to be closed, even tho i have it opened on my firewall and already ported it on my router

​

Is there anything i can do? Im willing to send screenshots of my configurations on both my router and my firewall if they get to fix the problem

    First, make sure that you’re not behind CGNAT with your carrier. Refer to the dozens of on-line articles for instructions on how to check.

    If you’re NOT behind CGNAT, then you might have one of a number of finicky routers that won’t port-forward from-and-to the same port number. I’ve run into several over the years.

    In those instances, pick a random port number from the high UDP range, (40000-60000) or so.

    Let’s say you pick 45678.

    Let’s also assume that your Minecraft server is at 192.168.1.200 on your LAN, and listening on port 25565.

    Go into your router, and configure the port forwarding rule like this:

    External IP: ____ Blank or 0.0.0.0 – whichever your router requires.

    External Port: __ 45678

    Protocol: TCP

    Internal IP: ____192.168.1.200 <<< Use your minecraft server IP here.

    Internal Port: __25565

    Save your settings, and restart your router.

    Then, have your friend(s) try connecting to: YourPublicIPAddress:45678

    See if that works. . .

    (Again, this won’t work if you’re behind CGNAT.)

    Ignoring port checker sites like, have you actually had someone from outside your network try to connect to the Minecraft server when it is running?

    Check for cgnat. Find the WAN/Internet IP address on your router status page. Compare it with whatismyip.com They should be the same. This is also the IP address people should be using to connect to your server

        Have you checked for cgnat?

        Also is there another router between the one you are doing port forwarding on and the internet?
