bo4rYou want to use your ipv4 address as your local IP which should be something along the lines of 192.168.1.xx with the x's being random numbers. To find this IP open up cmd and type in ipconfig. Your actual server IP that people connect to will be the IP that shows up when you google whatsmyip
Edit: your protocol should also be set to "both"
Edit 2: example https://gyazo.com/472740b15af61fe5bd5b7e1a09e7a2a8
it's setup like that, but yet nothing works
even my external ip with the :25565 port attached to it
