# Networking – blocking the ports

networkingportport-forwarding

How do I find out what is blocking my ports? I am on Windows 7 x64 and trying to run Minecraft on port 25565, which worked yesterday, but not today. I have not installed any new software.

I have tried disabling Windows firewall, and I previously added two days ago a port forwarding setting to my modem. Since it worked yesterday I don't think it has to do with my ISP.
