Can't access server even after port forward

[iMelsom]

You have to port forward from the public IP to the WebUI IP.

For an explanation of how NAT and port forwarding work, and why we need it see this answer on this thread:

How to let friends connect to my Server?

Thanks for the help but I have another question. I dont really understand how I can find my external IP on that wiki page, can’t I just go to whatismyip.org or something like that and use the IP that they show me there? What is the difference between internal and external? Kind regards GT
