视频会议的端口映射

关键字：

Polycom

端口映射

视频会议

中国作为一个

IPv4

地址奇缺的国家，

NAT

几乎是工作中中的必

备了。

我们经常会碰到只有一个公网

IP

，

里面却有不少的服务器需要

NAT

映射，这也罢了，多几行命令就好了。

但是碰到如

Polycom

的视频会议系统，就有一点点麻烦了，

因

为这个系统有多达

70

< br>多个端口需要映射。通过咨询

Polycom

的工程

师，这套系统需要映射

TCP/UDP

1 718~1720

，

TCP3230~3243,UDP

3230~3285

，此外，据说还需要

T CP1503(

此次没有加也测试成功

)

。

最不给力的，他说不保证能每次都能成功。不过不管如何，这次是成

功了。

以下是在

CISCO ASA5500

防火墙上做的映射和
