Having trouble making my minecraft server work when its not local

[Tedstonegenious]

I have a Minecraft server that I run on my computer. It is just for me and my sister. It works fine when she is here with her laptop, but she cannot connect when she is at my brother's house. She's living there so it's easier to go to college. It is a vanilla 1.13.1 server and I have not set up a domain. Shouldn't my computer's IP address be enough? These are the settings

Go in your router settings, port forward 25565 to your local IP. (192.168.x.xxx)

and it's not your computer/local IP, but the IP your ISP attribute to your modem that should be used to connect to you.

[Tedstonegenious]

can you give me detailed instructions? I do not know how to forward a port, but I am in the router settings.

[TetraSky]

Which router do you have?
It's usually in advanced settings, WAN> Port Forwarding or something similar to it(like Application and Gaming/Single Port Forwarding)
In there you choose UDP/TCP (or BOTH) for the Protocol, input your local computer's IP address for the Local IP to be used and in the port range field, you put the one used by minecraft server. Service name can be anything, or just "mcserv", doesn't matter. If it says "internal" and "external" port, just type in the same port.

thanks!

Another thing. What IP address should I give her? I just gave the one google tells me, and that apparently doesn't work

I did some reading, and apparently The switch between the router and my computer is making things complicated. what do I do.

Firstly you  should get your computer a static IP, this way it won't change all the time and the port forwarding won't be wrong. You c,an do this directly in windows or probably reserve it on your router. Then you also have to calculate that you're probably on a dynamic IP at your isp so you'll have to check this everyday and give her the new IP as it changes.

A switch doesn't make things complicated. It's just a box that connects computers to each other (operating at the data link layer) it just passes on the traffic between devices, in this case between the router and minecraft server.
