As you can see, the NAT router stores the IP address and port number of each computer in the address translation table.
正如你所见，NAT路由器将每台计算机的IP地址和端口号都存储在地址转换表中。
It then looks in the address translation table to see which computer on the stub domain the packet belongs to.
然后它查看地址转换表确定数据包是属于哪一台存根域中的计算机。
It changes the destination address to the one saved in the address translation table and sends it to that computer.
路由器将其目的地址换成它保存在地址转换表中的那个，然后将数据包发送到那台计算机。
The router then checks the address translation table to find if there is an entry existing for the inside local address with a corresponding inside global address.
路由器然后查看地址转换表，看有没有一个条目是这个内部本地地址对应的内部全局地址。
But since a typical entry in the address translation table only takes about 160 bytes, a router with 4 MB of DRAM could theoretically process 26,214 simultaneous translations!
但是由于通常的地址转换条目是160字节，而一台有4Mb大小dram的路由器理论上可以同时执行26214个地址转换！
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。
The translation table now has a mapping of the computer's non-routable IP address matched with one of the unique IP addresses.
现在，地址转换表就拥有了这台计算的不可路由IP地址到一个唯一 IP地址的匹配映射。
The translation table now has a mapping of the computer's non-routable IP address matched with one of the unique IP addresses.
现在，地址转换表就拥有了这台计算的不可路由IP地址到一个唯一 IP地址的匹配映射。
