New Computer- Port forwarding stopped working

I used to run all sorts of minecraft servers off of my old computer but that one was old and slow. Now I got a new computer and I wanted to get back to running servers and when I set up my port forwarding I cannot connect to the server. I know the port forwarding within the router is set up right, could there be firewall settings that I need to configure?
Thanks,

Possible Things Wrong with Port Forwarding:

1 - you don't have a Static IP Address and your IPV4 Address changed
2 - Check if the port is open correctly when your server is running at canyouseeme.org
3 - You didn't allow port 25565 through your firewall

Possible Server Problems:

1 - You have something set as your IP in your server.properties file
2 - Wrong Port Number

 

I didnt have it open in my firewall, i had forgotten to do that thank you!
