!!关于lvs的LinuxDirector直接暴露在公网的问题!!

看了很多关于lvs的试验介绍,可是都是介绍的linuxdirector服务器直接配置VirtualIP地址是公网地址,也就是把LinuxDirector直接暴露在了公网下,这样是很不安全的。生产环境下难道也是如此吗?是不是在LinuxDirector和公网之间应该有个IDS或者防火墙或路由器。如果那样,LinuxDirector的VirtualIP地址还能设置成公网地址吗?那么在LinuxDirector和Internet之间的IDS或防火墙或路由器就有了公网地址(也就是LinuxDirector需要的VirtualIP地址),那么IDS或防火墙或路由器应该如何设置呢,而LinuxDirector又该如何设置呢?
如下图附件所示,如果某公司具有固定公网IP地址214.3.21.x,那么这个地址也就是LinuxDirector需要设定的VirtualIP地址,但是我们在生产环境下肯定不可能把LinuxDirector直接暴露出来,那么我们该怎么处理呢?麻烦大家可否给出一个具体的设定范例,多谢!

维护好的LinuxDirector本身就像防火墙一下,它安全性应该不成问题。如果在前端安装一个出入必经的防火墙,那么防火墙可能会成为整个系统的瓶颈。

就我所知,很多实际的LinuxDirector应用都是直接带公网的IP地址。
