I just noticed that only the UDP ports are opened on all the port forwarding rules the fios router had using the primary router port forwarding too. For example port 35000 TCP is closed, port 35000 UDP is opened. Is that the way is supposed to happen or there is something not working properly? Is there a difference between UDP and TCP? Does it matter if it's UDP or TCP? All the UDP ports are opened, all the TCP ports are closed, why is that?
