当一台在存根域 (网络) 中被分配了内部本地地址的计算机想要和外部网络通信时，数据包就会像通常一样被路由到其默认网关，此时网管充当NAT路由器功能。
When a computer on the stub domain that has an inside local address wants to communicate outside the network, the packet goes to one of the NAT routers by way of normal routing to the default-gateway.
这台计算机接收来自路由器的数据包，并且只要这台计算和外部网络通信，此过程就会重复执行。
The computer receives the packet from the router and the process repeats as long as the computer is communicating with the external system.
这是Snort最基本的功能，以包的形式检测和观察网络通信量是所有其他功能的基础。
This is probably Snort's most basic function, and everything else it does depends on this ability to detect and observe network traffic in a packet form.
因为网络通信流常常通过不可信的网络传输(考虑一下您喜欢的wifi热区)，数据包很容易被捕获，所以应该使用SSL加密重要的We b通信流。
Since network traffic is often traveling over untrusted networks (consider your favorite WiFi hotspot), where capturing packets is quite easy, important Web traffic should be encrypted using SSL.
这些停放车辆具有无线通信设备和高容量汽车电池，可以很容易地加入到车用自组织网络通信中来，并像静态路由器一样中继和转发数据包。
These parked vehicles have wireless device and high volume battery, and can easily participate in vehicular communications and serve as stationary routers to store and forward data packets.
