Hello
Apologies: I cannot speak German, so I must post in English.
I have a Gen7 root server with Centos 7, I'm trying to configure IPV6. I have followed the instructions in the wiki, configured the firewall, and rebooted the server.
I cannot get any IPV6 connection, not even to the gateway.
Attached: ifcfg-eth0 ifcfg-eth0.txt, 50-IPV6.conf 50-IPv6.txt
For the firewall I have firewalld and added ipv6-icmp protocol like so:
firewall-cmd --permanent --add-protocol ipv6-icmp
firewall-cmd --list-all
public (active)
target: default
icmp-block-inversion: no
interfaces: eth0
sources:
services: dhcpv6-client ... &c
ports:
protocols: ipv6-icmp
masquerade: no
forward-ports:
source-ports:
icmp-blocks:

The interface looks normal
ip addr show eth0

The routing table appears to be badly broken

Which results in not being able to ping the gateway
ping -6 -I eth0 fe80::1

From fe80::d8de:dcff:fee5:ac15%eth0 icmp_seq=2 Destination unreachable: Address unreachable
The other strange thing is that I cannot traceroute/ping from outside

It seems to me that I should be able to get further than that (I think anexia-it.net is netcup?)
Does anyone have an idea what I can try next? Should I open a ticket?
Many thanks!
