Hello, I'm trying to set up a Minecraft server , but I seem to be doing something wrong when I try to port forward (I've had a Server before and it worked just fine with the same settings (this was before I got a new Motherboard and a CPU)).
After upgrading the CPU and the Motherboard The ports seem to no longer be forwarded. I also had format the HDD before I re-installed windows (could this have something to do with the problem?). So what should I do?

You forward the ports on the router, not the PC. Please provide more details so we can help further.

Did you change any settings on the router?
Are you using the same IP address as before? Changing the motherboard will likely cause your router to give you a different IP address.

Well, all I did on the router was port forwarding, I found out my IP adress using sites like http://www.whatismyip.com/ .
And I for the server i opened the port 25565 which should be the default port for Minecraft

Oh, and this might help: I tried adding my IP after the "IP="on the server config file. And now when I try to run the server it says this: "[Warning] **** Failed to bind to port, the exception was: java.net.BindException: Cannot assign requested address JVM_bind , prehaps a server is already running on that port?" . So, does that mean I'm using the wrong IP?

Open up a command prompt and enter:

ipconfig

That will tell you your actual IP address you need to use when you tell the router to forward ports.

You have something else running on that port, restart your pc!
