Port Forwarding Help

Sorry if this is the wrong section, first post

On my old computer I hosted a Minecraft server for myself and several friends.

I recently got myself a new PC running Windows 8. None of my friends can connect to my server and I suspect this is because of port forwarding. How can I open the port so my friends can connect to the server?

Well I'm going to assume you have already forwarded the port in your router to your local ip address. From that point, you need to go into your Windows Firewall and create a custom rule for the Minecraft Port you are using allowing it to pass through the firewall.

Configure Windows 8 Firewall
