I'm trying to get IPv6 to work.
My host provied me the following informations:
IPv6 network: 2a03:4000:2:483::/64
IPv6 gateway: fe80::1

My /etc/network/interfaces looks like this:

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug eth0
iface eth0 inet dhcp

#IPV6 static configuration
iface eth0 inet6 static
pre-up modprobe ipv6
address 2a03:4000:2:483::2
netmask 64
gateway fe80::1
# END IPV6 configuration

And ifconfig outputs the following:

eth0      Link encap:Ethernet  HWaddr 52:54:7e:5a:c2:b4
          inet addr:  Bcast:  Mask:
          inet6 addr: fe80::5054:7eff:fe5a:c2b4/64 Scope:Link
          inet6 addr: 2a03:4000:2:483::2/64 Scope:Global
          RX packets:173542 errors:0 dropped:0 overruns:0 frame:0
          TX packets:27863 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:10582552 (10.0 MiB)  TX bytes:1658598 (1.5 MiB)

ip -6 route show outputs:

default via fe80::1 dev eth0  metric 1024

And route -6:

ping6 results in

The server is running Debian 3.2.51-1. I hope you can help me with this.

try ping6 sometimes being explicit helps. Aside from that this GW address fe80::1 seems a bit strange. this range has been set aside for link local addresses and should not be used for GW stuff. – zeridon Feb 7 '14 at 12:43
@zeridon: link-local addresses are very often used for gateways. That is one of its purposes. Take a look at a machine that got its default GW from a Router Advertisement. It will be a link-local address, and it will work just fine. – Sander Steffann Feb 7 '14 at 13:11
@Kimmax: Check your firewall settings. I wouldn't be surprised if your (default?) firewall is blocking IPv6 traffic. Note that for IPv6 you have to use ip6tables instead of iptables – Sander Steffann Feb 7 '14 at 13:12
link-local addresses are fine for gateways, but you still need to confirm that you have the right address for the gateway. Where is the router in all this? – Paul Feb 7 '14 at 13:25
I set up the ip6tables with help of this doc: Is this right? – Kimmax Feb 7 '14 at 13:32
