语音数据报NAT/FW隧道穿越的实例研究

IP网络上的语音应用已经非常普遍,语音数据报在网络上如何传输,并不被人们熟知,尤其是语音数据报如何在内网与外网之间进行NAT/FW隧道穿越是许多网络技术专业人士关心的技术。因此,本文简明地阐述了语音数据报NAT/FW隧道穿越的原理,较详细地给出了其实现过程及配置。

The voice applications are very popular on IP network.Voice packet transmission on the network is not to be familiar.In particular,it is the technology of many network professionals who care about that the NAT/FW tunnel through between the internal network and external networks.Therefore,this article succinctly describes the principle about how the voice packets through,and gives in detail the process of its implementation and configurations.
