Hello, blocking ports is subject to the logic you program with TunTap. Once the IP packet arrives as a buffer, you have to parse it, read the IP header and the port, and then simply not forward it to the other party. So, you have to build an IP router. I'd be happy to show you an example in Java for another project that shows exactly what this does. The description also states that they block broadcasts to 255.255.255.255 to reduce internet traffic.
