所需软件：libupnp-1.3.1.tar.gz、linuxigd-1.0.tar.gz，sourceforge 上都有，下最新版的
先安装 libupnp，按照 INSTALL 做就可以
后安装 linuxigd，也就是 Linux 下的 daemon 程序，upnpd
根据 INSTALL 的提示，可以选择有 libiptc 的情况，我的系统也确实有，是在编译 iptables 的时候生成的一个动态链接库，但编译后发现创建 PortMap 错误，于是去掉了 libiptc 的支持
另，INSTALL 里提示要加组播路由并在 INPUT 里允许组播地址进入，这个是一定要做的，否则有的软件无法通过。

其中 nat 表 PREROUTING 链里面以及 filter 表 FORWARD 链里面的内容是 upnpd 自动添加的。
经过测试，迅雷软件必须在有组播路由的情况下才能使用，比特精灵则怎么都无法通过，而 eMule 是能力最强的，无论是否加组播路由都可以识别并使用 IGD 的 UPnP。
