我有一台 Debian Jessie 驱动的服务器，它充当我们家庭网络的路由器。我已成功使用 TunnelBroker 设置 IPv6 隧道，并且traceroute命令成功返回。
以下是我的路线表和输出ip -6 addr
~$ ip -6 route

一个简单的traceroute命令返回以下内容：

我似乎已成功配置为分发 IPv6 地址，如我的 Windows 8.1 Pro 桌面的响应radvd所示：ipconfig
Ethernet adapter Ethernet:
Connection-specific DNS Suffix . : example.com
IPv6 Address. . . . . . . . . . . : 2001:470:1f14:904:a05b:6fd2:b36b:f9af
Temporary IPv6 Address. . . . . . : 2001:470:1f14:904:d40d:78ad:a2db:30cc
Link-local IPv6 Address . . . . . : fe80::a05b:6fd2:b36b:f9af%2
IPv4 Address. . . . . . . . . . . : 192.168.10.6

Default Gateway . . . . . . . . . : fe80::218:71ff:feea:f57b%2
192.168.10.1
但是，当我尝试对 ipv6.google.com 执行操作时tracert，请求超时；
C:\>tracert -6 -h 10 ipv6.google.com
Tracing route to ipv6.l.google.com [2a00:1450:4013:c00::64]
over a maximum of 10 hops:
1 * * * Request timed out.
2 * * * Request timed out.
3 * * * Request timed out.
4 * * * Request timed out.
5 * * * Request timed out.
6 * * * Request timed out.
7 * * * Request timed out.
8 * * * Request timed out.
9 * * * Request timed out.
10 * * * Request timed out.
现在的问题是：如何让我的 LAN 客户端使用 Linux 路由器上的隧道？
我已经做了一些挖掘，但可能就是找不到正确的搜索词来解决我的问题。
编辑：添加radvd配置
interface eth1
{
AdvSendAdvert on;
MinRtrAdvInterval 5;
MaxRtrAdvInterval 15;
prefix 2001:470:1f14:904::2/64
{
AdvOnLink on;
AdvAutonomous on;
};
};
答案1
一些想法：
- 您是否已启用 ipv6 路由（sysctl -w net.ipv6.conf.all.forwarding=1）；可能需要为每个 intf 执行此操作
- 您的 he-net 隧道是否会转发/接受您提供给客户端的 IPv6 地址？如果没有，您将需要 NAT。
