我有1and1的服务器，我正在尝试使用一组静态IPv6地址进行设置 . 我无法让它工作，并尝试了我可以在谷歌上找到的每个论坛和指南 .

这是相关的配置文件：

cat / etc / sysconfig / network

NETWORKING=yes
NOZEROCONF=true
GATEWAY=10.255.255.1
NETWORKING_IPV6=yes
IPV6FORWARDING=yes
IPV6_AUTOCONF=no
IPV6_AUTOTUNNEL=no
IPV6_DEFAULTGW=fe80::1
IPV6_DEFAULTDEV=eth0

cat / etc / sysconfig / network-scripts / ifcfg-eth0

DEVICE=eth0
BOOTPROTO=static
ONBOOT=yes
NAME=""
NM_CONTROLLED=no
MACADDR=""
MTU=1500
IPADDR=74.208.218.179
NETWORK=74.208.218.179
NETMASK=255.255.255.255
BROADCAST=74.208.218.179
IPV6INIT=yes
IPV6ADDR=2607:F1C0:812:7d10::/56
IPV6ADDR_SECONDARIES="2607:F1C0:812:7d10::1/56 2607:F1C0:812:7d10::2/56 2607:F1C0:812:7d11::/56"
IPV6FORWARDING=yes
IPV6_DEFAULTGW=fe80::1

我已经通过sysctl在内核中设置了IPv4和IPv6的转发：

cat /etc/sysctl.conf

net.ipv4.ip_forward=1
net.ipv4.tcp_syncookies=1
net.ipv4.conf.default.rp_filter=1
net.ipv4.conf.default.accept_source_route=0
net.ipv6.conf.all.forwarding=1
net.ipv6.conf.all.accept_ra = 0
net.ipv6.conf.all.autoconf = 0
kernel.shmmax=68719476736
kernel.msgmax=65536
kernel.msgmnb=65536
kernel.sysrq=0
kernel.shmall=4294967296
kernel.core_uses_pid=1

这是一些命令的输出：

使用此设置，我无法ping ipv6.google.com甚至默认网关：

ping6 ipv6.google.com

PING ipv6.google.com(ord08s12-in-x14.1e100.net) 56 data bytes
^C
--- ipv6.google.com ping statistics ---
4 packets transmitted, 0 received, 100% packet loss, time 6052ms

ping6 fe80 :: 1

connect: Invalid argument

[Update] I was unable to ping the link local address fe80::1 
because I hadnt included the interface option. 
ping6 fe80::1 -I eth0 works. However, I still cannot ping outside 
the local network.

Traceroute6给出以下输出：

traceroute6 fe80 :: 1

问题是网关是fe80 :: 1而我的ipv6地址是2607：f1c0：812：...？
