我的设置是基本的，你可以得到。 我在dom0（Debian Squeeze），eth0和eth1上有2个接口。 我为eth1创build了一个桥接，将数据包转发到具有公共IP地址的domU。 我可以通过外部连接（ssh）到dom0，但是我无法从外部访问domU。 我试图自己configuration大部分networking堆栈，所以xend-config.sxp唯一启用的是(vif-script vif-bridge) 。 我错过了什么？
假设xyz是我公有 IP的前缀。

两件事情。 我通常把IP地址放在桥上。 另外，我不使用这个场景的xendconfiguration文件。
在这里看一个例子:(你可以修改它来使用eth1）
