How to forward ports to the local IP of my laptop?

[Ziggy Plock]

I've tried port forwarding in order to get HighID with limited success

At my house, i followed all the steps for my router (a ZTE model H369A) at the port forward site and then it woked, I had a static IP address.

But at my friends house it doesn't work.

I think I am failing at forwarding the ports to the local IP of my laptop.

I can't find [A] WHAT the local IP of my laptop is, and WHERE i should enter that IP address in my friends routers page.

So, how do i do both?

Thanks.
Router is a ZTE model H369A, and an issue might be that it has some sort of firewall which I don't know about.


EDIT: I figured it out already. If anyone's interested, please ask.
