Ok, first off I'm sorry I know Its been posted many times.
I cannot get port 25565 forwarded. I want to run a survival multiplayer server online for me and my cousin.
I'm using a ATT 2wire router/modem. I go into firewall , drop the box to my laptop I'm using , add the application that is minecraft with port 25565 open. Then I click done. As far as I can tell this should be all good to go.
Ask me as many numbers etc you can I will post anything you need. Im currently trying to find somewhere to upload a photo I made with Everything on it.
