My server can't ping/reach any other outside.
ping6 works for my local fe80::468... address as well as the 2a01:4f8..., but not for fe80::1!

Errors/Troubles/Issues:

ip neigh show 
fe80::1 dev eth0  FAILED

ping6 2001:4860:4860:8888 (Google)

Setup

ip -6 a 
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 2a01:4f8:202:43d5::2/64 scope global
      valid_lft forever preferred_lft forever
    inet6 fe80::468a:5bff:fe2c:3d6a/64 scope link
      valid_lft forever preferred_lft forever

ip -6 route

2a01:4f8:202:43d5::/64 dev eth0  proto kernel  metric 256  pref medium
fe80::/64 dev eth0  proto kernel  metric 256  pref medium
default via fe80::1 dev eth0  metric 2  pref medium



Any ideas how to solve this?

  • Why do you use fe80::1 as a gateway? That is probably wrong. Ping all routers and you should receive a response from the actual gateway address: `ping6 -c 1 -I eth0 ff02::2` – Michael Hampton Feb 23 '16 at 22:36
  • Because this gateway was the default at my controlpanel and rescue-system. `ping6 -c 1 -I eth0 ff02::2` results in 100% packet loss. – am1 Feb 23 '16 at 22:44
  • You should contact Hetzner. It looks like something is wrong with their stuff. – Michael Hampton Feb 23 '16 at 22:47
  • @MichaelHampton The dedicated servers I have at Hetzner use `fe80::1` as the default gateway. The vservers I have at Hetzner use a routable IPv6 address as the default gateway. – kasperd Feb 26 '16 at 09:33
  • @ambiente1 Does it work if you use `2a01:4f8:202:43d5::1` as gateway? – kasperd Feb 26 '16 at 09:34
