我怎样才能从我的tun0接口转发IPv6stream量到eth0接口？
使用ifconfig：
eth0 Link encap:Ethernet HWaddr 00:16:3E:12:77:54 inet addr:208.111.39.160 Bcast:208.111.39.255 Mask:255.255.255.0 inet6 addr: 2607:f740:0:3f::eda/64 Scope:Global inet6 addr: fe80::216:3eff:fe12:7754/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:65590 errors:0 dropped:499 overruns:0 frame:0 TX packets:40111 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:13246038 (12.6 MiB) TX bytes:28807669 (27.4 MiB) Interrupt:29 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) tun0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 inet addr:10.8.0.1 PtP:10.8.0.2 Mask:255.255.255.255 inet6 addr: 2607:f740:44:22::8/64 Scope:Global UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1 RX packets:16876 errors:0 dropped:0 overruns:0 frame:0 TX packets:16504 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:2235766 (2.1 MiB) TX bytes:7680377 (7.3 MiB) 我启用转发：
[root@baobei ~]# sysctl net.ipv6.conf.all.forwarding net.ipv6.conf.all.forwarding = 1
防火墙：
ip6tables -F INPUT ip6tables -F FORWARD ip6tables -F OUTPUT ip6tables -F ip6tables -P INPUT ACCEPT ip6tables -P FORWARD ACCEPT ip6tables -P OUTPUT ACCEPT echo -n "1" >/proc/sys/net/ipv6/conf/all/forwarding echo -n "1" >/proc/sys/net/ipv6/conf/all/proxy_ndp echo -n "0" >/proc/sys/net/ipv6/conf/all/autoconf echo -n "0" >/proc/sys/net/ipv6/conf/all/accept_ra ip6tables -A INPUT -p icmpv6 -j ACCEPT ip6tables -A FORWARD -m state --state NEW -i tun0 -o eth0 -s 2607:f740:44:22::/64 -j ACCEPT ip6tables -A FORWARD -m state --state ESTABLISHED,RELATED -j ACCEPT
路线：

但是，到达tun0接口的ipv6数据包不会路由到eth0接口。 感谢您的任何帮助，build议。
这是一个简单的路由问题。 你的路由表，没有任何路由来通过tun0接口引导stream量，所以没有任何东西被转发。
我收集你正在使用OpenVPN。 据我所知，OpenVPN的IPv6支持不包括redirect-gateway选项的IPv6等价物。 您可能需要添加自己的路由与从服务器推送的route-ipv6语句。
