大佬教程收集整理的这篇文章主要介绍了linux – IPv6仅在ping到路由盒后才能工作，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
我们的网络中只有一个ipv4路由器,每台计算机都连接到它(wifi或有线电视).
具有ipv4和ipv6的服务器也连接到此路由器.服务器已配置隧道经纪人,用于6to4隧道和radvd.网络中的客户端具有正确的前缀,可以通过ipv6互相ping通.但是在他们第一次ping服务器(带有隧道的服务器)之前,他们无法ping到互联网.
我找到了某个地方,这是一个icmp问题,但我找不到解决方案.
问题是路由器只是ipv4吗？
>服务器和客户端运行linux
>路由器运行dd-wrt没有ipv6支持:(
