让你的家庭也接入IPV6网络吧。
为什么我们中国的网络发展总是那么的滞后呢？
为什么我们国家的CNNIC总在叫着要加快IPV6的步伐！ 可是却没有任何进展？？
我们也不去报怨了。 现在让我们的家庭也接入IPV6吧。（不是指某一台机器哟）
要想让你的家庭也接入IPV6网络。肯定得有一段地址吧！ 这个简单 申请吧！ （是不是在想我去哪儿申请呢？ ）
去国外申请。 为什么要去国外。 因为国外拥有大量的IPV6地址。人家的地址段可以约等于我们的地址位。
openvpn in Linux (FC5)
[root@localhost src]# gzip -dc openvpn-2.1.1-ipv6-0.4.10.patch.gz | patch –p1
ifconfig eth0 add 2005::4/64
route –A inet6 add default gw 2005::1
加入 /etc/rc.d/rc.local
cp /etc/sysconfig/network-script/ifcfg-eth0 /etc/sysconfig/network-script/ifcfg-eth0:1
Change device eth0 ==>eth0:1
OpenVPN 2.1.1 use bridge (TAP Driver)
dev tap0 (根据实际情况调整。)
Server-bridge 192.168.8.4 255.255.255.0 192.168.8.20 192.168.8.250

OpenVPN and CentOS 5 Installation and Configuration Guide
Many ppl found that installing VPN on linux is not that easy, the abvailable installation guides on VPN is often limited. I have tried a lot of installation guides and finally get it connected successfully.
Here are the steps to guide you installed a secure connection between your? CentOS5 and Windows with OpenVPN open source application.
win7 会自动创建IPV6隧道？
最近在配置OpenVPN服务器，准备拿来做为IPV6 用户远程接入。当我在本地计算机上测试网络联通性时，突然发现 我不会开任何的IPV6工具软件。也能PING通IPV6地址。
我计算机的系统是：
我的网络是： 内网环境 （IPV4地址为：192.168.77.*/24)
当时我正准备用PING测试一下服务器的IPV6地址能不能通，但是又忘了开启IPV6接入软件。 却惊奇的发现可以PING同服务器。
