Since the NAT router now has the computer's source address and source port saved to the address translation table, it will continue to use that same port number for the duration of the connection.

由于nat路由器现在已经拥有了这台计算机保存在地址转换表中的的源地址和源端口号，它将会在有效期内继续使用同一个端口号进行转换。

So any external network sees the NAT router's IP address and the port number assigned by the router as the source computer information on each packet.

这样任何一台处于外部网络的计算机都会在发送给它的数据包里找到NAT的IP地址和由路由器分配的端口号。
