I have a server at 1and1 that I'm trying to setup with a set of static IPv6 addresses. I can't get it to work and have tried every forum and guide I could find on google. Their tech support has told me that the gateway is fe80::1. The IPv6 addresses I'm trying to use have been provisioned using the 1and1 control panel and are assigned to my account. IPv4 networking is setup and working fine, I just need help with IPv6.

Here's the relevant configuration files:

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

I've setup forwarding for both IPv4 and IPv6 in the kernel via sysctl:

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

Here's the output of some commands:

Using this setup, I can ping the default gateway but not anything outside of the 1and1 network:

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

Is the problem that the gateway is fe80::1 and my ipv6 addresses are 2607:f1c0:812:...? I did have trouble getting the IPv4 setup working since my IPs (74.208..) were on a different subnet than the gateway (10.255.255.1).


Side Note: If it helps anyone else out there on a 1and1 server, for IPv4, you'll need to modify /etc/sysconfig/network-scripts/route-eth0 like so:

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

  • I would expect to see the default gateway on your own network. Did the provider tell you that fe80::1 should be your default gateway?

  • @MadHatter Yes. I had emailed 1and1 Tech Support and was told the default gateways were IPv4=10.255.255.1 and IPv6=fe80::1. Both gateways were not on the same network, but IPv4 is the only one I can get working.

  • Fair enough....

The setup was correct. For anyone else out there with a 1and1 dedicated server, the only way I could get any traffic through is to completely deactivate the 1and1 IPv6 firewall via their control panel. Modifying the rules did not make a difference.
