Port forwarding is important if you have applications or games that require an unobstructed connection from a computer on your local network to a remote service or server. What it basically does is open a port in your firewall and direct all traffic that is sent to that port to a specific computer on your network. Think of it as opening a secret entrance in your city wall and then routing all traffic that goes through it to a specific house.
If you do not set up port forwarding for your application, it may not be able to connect to the service or you may have to live with reduced performance.
