Why can't my brother on my Minecraft server?

I have the following problem:

My brother, a few friends and I want to play Minecraft on a server together, I can figure it out but my brother and my friends (all in the other network) are not on it they always get the message that the connection could not be made.

Where is the mistake?

Could that be that your friend and brother use the same Minecraft Accaount? If so, then I do not need to be surprised.

Vlt you first tell, where the server is operated (Internet server / home server?) What did you tell them so that they can connect? Do you have a withelist active? Ect… There were glass balls, but they are not anymore. Sorry…

Ne each his own, if you log in with the same account (on the server) you will be kicked out.

Then this may be that the public server does not allow multiple players with the same IP pure joins. My tip: Download your own Minecraft Server, and have your own server where you (with the help of plugins) z. B. Make your own beadwars game.

I run the server on my computer (Spigot), I have given the IP address with which I can also join

The server is running on my PC (downloaded from https://getbukkit.org/get/68aef01121494a41fe71890b81d69d07), but I thought that each have their own IP address?

The IP with which you join is an internal IP that is only available and accessible within your network. The computer has an IP, and the MC server also has a port to… You must enter in the Internet router the port and the IP as a share. Then you have to give your friends / brother the InternetIP that your router has been assigned by the provider and the port.

Example: PC has 192.168.1.15 / server port is 56658, then in the router the port forwarding / port release must be set up as follows:

TCP port 56658 to destination address 192.168.1.15 port 56658

The whole thing again for UDP…

Then you go to "wieistmeineip.de" and look at the address that is displayed there. Example 212.13.112.20. Your friends then you give this IP and the port 56658. As a server must enter in MC then 212.13.112.20:56658.

Achrung! Many providers disconnect every 24 hours and assign a new address. Same if the router restarts. So always look ahead, if the address has changed. Alternatively, set up a DynDNS service that updates the destination address in the DynDNS service via the router (if supported) or a program that also runs on the PC…

Thanks, but the IP address I'm on the router does not release the IP address of my computer

No. The router gets a public IP… What is distributed behind IPs from the router, you can't see from the outside and not reach, unless a port forwards to a specific IP… So the router blocks all requests that come from outside, if these can't be assigned to an internal IP by a unique port. Your private IP is thus ONLY within your network directly accessible. Everything that comes from the outside must use the RouterIP and the shared port.

It is different with the inquiries, which go out from the PC. The router automatically remembers which IP has made which request. The answer from the outside comes then only on the router IP, and knows by the internal request, to whom the answer belongs…

Ok, so I have to share my IP address from my PC and the port from my server on the router. My brother / friends, I must then give the RouterIP including the port. Is that correct?

Japp, that's right. I already did that too. Works flawlessly…

Thank you.

I will try it.

Can it be that you have not released a port in your router? Because otherwise they can't do that unless you use Hamachi or a Hamachi alternative.

Can you help me one more time?
I did that now, but it still does not work. I once sent a picture in response, where you can see how I have released the port on the router. But if I give my friends the IP address, which is in the picture under "IP address on the Internet" to find and the port "25565" can still not on it. The IP address which can be found in the picture (under "IP address on the Internet") is the same as in "wieistmeineip.de"
