这题目主要问你下面哪个地址会作为源地址出现在路由器到destination server的数据包中.
看图中有配置,路由器配置了动态NAT,这里配置的NAT,就是把10.10.0.0与地址池199.99.9.40 到199.99.9.62相关联.把S1定为在外部,FA0口定在内部.
当PC机上发起FTP时,经过路由时出去时就会把内部的地址由NAT转换.就会把10.10.0.0网段中的地址映射成为199.99.9.40到199.99.9.62中的地址.因为PC机的地址都是10.10.0.0中的网段地址.所以很容易得出答案,能作为路由器的源地址只能是199.99.9.40到199.99.9.62中的其中一个地址.只能是答案D了.
