情况

我知道如何进行 ipv4 转发,并期望 ipv6 转发的工作方式基本相同。因此,我使用从我的 ISP 配置的网络地址配置了 VirtualBox 主机。目前,这是我拥有的网络:

问题

我可以 ping 通 Debian 路由器上的所有 ipv6 地址,但无法访问 Debian 必须转发数据包的地址,例如从 Fedora 客户端到 Debian 上的 eth0。

配置

Debian 服务器配置为允许 IPV6 转发:

root@6server:~# sysctl -p
net.ipv6.conf.all.forwarding = 1
net.ipv6.conf.all.accept_ra = 2
net.ipv6.conf.all.accept_redirects = 1
net.ipv6.conf.all.accept_source_route = 1

Iptables 也应该允许它..

root@6server:~# ip6tables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination         

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         
ACCEPT     all      anywhere             anywhere             state RELATED,ESTABLISHED
ACCEPT     all      anywhere             anywhere            

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination         

这是我的地址和路线信息:

root@6server:~# ip -6 addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000
    inet6 2001:981:ec6a::aa:0/48 scope global 
       valid_lft forever preferred_lft forever
    inet6 fe80::a00:27ff:fed6:b45c/64 scope link 
       valid_lft forever preferred_lft forever
3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000
    inet6 2001:981:ec6a::ae:1/48 scope global 
       valid_lft forever preferred_lft forever
    inet6 fe80::a00:27ff:fe77:f6e8/64 scope link 
       valid_lft forever preferred_lft forever

root@6server~# ip -6 route show
2001:981:ec6a::aa:0/112 dev eth0  metric 1024 
2001:981:ec6a::ae:0/112 dev eth1  metric 1024 
2001:981:ec6a::be:0/112 dev eth1  metric 1024 
fe80::/64 dev eth1  proto kernel  metric 256 
fe80::/64 dev eth0  proto kernel  metric 256 
default via 2001:981:ec6a::2 dev eth0  metric 1024 

在 Fedora 客户端上,网络路由如下:

[root@localhost henk]# ip -6 route show
2001:981:ec6a::/48 dev enp0s3 proto kernel metric 256
fe80::/64 dev enp0s3 proto kernel metric 256
default via 2001:981:ec6a::ae:1 dev enp0s3 metric 1024
