I made a MC Forge server (same issues with vanilla, tried) and no-one else but me can connect to it. The port is standard, 25565 and I specificaly opened on both Windows Firewall and my router. I left the IP address blank, but that same issue happenes when i make it use my internal IP. When a client tries to connect it times out. I don't know what to do. I am on Windows 7 btw.
