. Instead, it uses the original allocated port number 62000. The previous NAT is called NAT, and the latter is called NAT. We expect that our NAT is the second type. If your NAT is the first type, many P2P software may fail. (Fortunately, most of NAT now belongs to the latter, that is, Cone NAT.) Well, we can see that through NAT, it is easy to connect computers in the subnet to the outside (NAT is transparent, and computers in the subnet and the Inte
