在1and1专用服务器上无法使用CentOS6静态获取IPv6设置

我在1and1有一台服务器，我正在尝试使用一组静态IPv6地址进行设置。我不能得到它的工作，并尝试每一个论坛和指导，我可以find谷歌。他们的技术支持告诉我，网关是fe80 :: 1。我尝试使用的IPv6地址已经使用1and1控制面板进行了configuration，并已分配给我的帐户。 IPv4networking设置和工作正常，我只需要帮助与IPv6。

以下是相关的configuration文件：

猫/ etc / sysconfig /networking

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IPv4和IPv6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

以下是一些命令的输出：

使用ifconfig

路由-n -A inet6

使用这个设置，我可以ping默认网关，但不能在1and1networking之外的任何东西：

ping6 fe80 :: 1 -I eth0

 64 bytes from fe80::1: icmp_seq=1 ttl=64 time=0.442 ms 64 bytes from fe80::1: icmp_seq=2 ttl=64 time=0.447 ms 64 bytes from fe80::1: icmp_seq=3 ttl=64 time=0.450 ms ^C

ping6 ipv6.google.com

Traceroute6提供以下输出：

traceroute6 ipv6.google.com

问题是网关是fe80 :: 1，我的ipv6地址是2607：f1c0：812：…？由于我的IP（74.208 …）与网关（10.255.255.1）位于不同的子网，所以我确实无法使IPv4设置正常工作。

注意：如果在1and1服务器上为IPv4提供帮助，那么需要像这样修改/ etc / sysconfig / network-scripts / route-eth0：

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

 ADDRESS0=10.255.255.1 GATEWAY0="" NETMASK0=255.255.255.255 ADDRESS1=0.0.0.0 GATEWAY1=10.255.255.1 NETMASK1=0.0.0.0

设置是正确的。对于那些使用1and1专用服务器的人来说，我可以通过其控制面板完全禁用1and1 IPv6防火墙。修改规则并没有什么区别。
