Normally, high ports are being used for outgoing connections (and the replies to them). So if you open a connection to, say, a web server on the internet your browser or App or other software will open a random high port and listen to it for the reply from the server. Routers detect this and keep the port open only for replies from the server the request was sent to, that's how NAT traversal works for outgoing connections. If the reply comes from another machine or takes too long the router might close the port or it might get used by another machine on your local network.
