既然如此，我们就好好的来探索一下 Linux 的网络世界吧！首先， Linux 到底可以达成哪些网络功能呢？这可就 多着咯！不论是 WWW, Mail, FTP, DNS, 或者是 DHCP, NAT 与 Router 等等，Linux 系统都可以达到，而 且，只要一部 Linux 就能够达到上面所有的功能了！当然，那是在不考虑网络安全与效能的情况下，你可以使用一 部 Linux 主机来达成所有的网络功能。 Tips: 由于网络卡卡号是跟着网络卡走的，并不会因为重灌操作系统而改变， 所以防火墙软件大多也能够针对网络 卡来进行抵挡的工作喔！ 不过抵挡网卡仅能在局域网络内进行而已，因为 MAC 不能跨 router 嘛！！ 为什么资料量最小要 46 最大为 1500 bytes 呢？ 讯框内的数据内容最大可达 1500bytes 这我们现在知道了，那为何要规范最小数据为 46bytes 呢？这是由于 上面跑吧？你无法确认所有的网络媒体都是支持那么大的 MTU 对吧！ 如果你的 9000 bytes 封包通过一个不支持 Jumbo frame 的网络媒体时，好一点的是该网络媒体 (例如 switch/router 等) 会主动的帮你重组而进行传送，差一点的可能就直接回报这个封包无效而丢弃了～这个时候可 就糗大啰～ 所以， MTU 设定为 9000 这种事情，大概仅能在内部网络的环境中作～举例来说，很多的内部丛集系

In many cases, the Gateway Address will be that of a router on the same network, which will in turn pass traffic on to other networks or hosts, such as Internet
