Been trying to configure ipv6 on my proxmox server for about an hour now and I just can't seem to get it right.

/etc/network/interfaces:

auto lo
iface lo inet loopback

auto vmbr0
iface vmbr0 inet static
    address xxx.xxx.xxx.2
    netmask 255.255.255.0
    gateway xxx.xxx.xxx.1
    bridge_ports eth2
    bridge_stp off
    bridge_fd 0

iface vmbr0 inet6 static
    address 2604:xxxx:xxxx:xxxx:0000:0000:0000:0002
    netmask 64
    gateway 2604:xxxx:xxxx:xxxx:0000:0000:0000:0001

ip -6 route

2604:xxx:x:2::/64 dev vmbr0  proto kernel  metric 256  mtu 1500 advmss 1440 hoplimit 0
fe80::1 dev venet0  proto kernel  metric 256  mtu 1500 advmss 1440 hoplimit 0
fe80::/64 dev venet0  proto kernel  metric 256  mtu 1500 advmss 1440 hoplimit 0
fe80::/64 dev eth2  proto kernel  metric 256  mtu 1500 advmss 1440 hoplimit 0
fe80::/64 dev vmbr0  proto kernel  metric 256  mtu 1500 advmss 1440 hoplimit 0
default via 2604:xxx:x:2::1 dev vmbr0  metric 1024  mtu 1500 advmss 1440 hoplimit 0

ping6 google.com

PING google.com(dfw06s46-in-x0e.1e100.net) 56 data bytes
From 2604:xxx:x:2::2 icmp_seq=2 Destination unreachable: Address unreachable
From 2604:xxx:x:2::2 icmp_seq=3 Destination unreachable: Address unreachable
From 2604:xxx:x:2::2 icmp_seq=4 Destination unreachable: Address unreachable

Would appreciate any help that could be provided. It is probably something pretty simple but I am a bit new to debian.

    /128 is not a valid prefix length on an ethernet, ethernet-like, or other multi-access device. That's only valid on loopback and point-to-point interfaces. The correct prefix length has to be something else, most likely /64. – Celada Mar 3 '15 at 3:28
  • Thanks I wasn't aware of that. Now i have gotten a bit further and just get "Destination unreachable: Address unreachable" on pings – awmusic12635 Mar 3 '15 at 4:39

    Please edit your question to show the new prefix length being used, and revise the output of ip -6 route because now it's probably different than it was before. – Celada Mar 3 '15 at 5:07
  • Updated as requested – awmusic12635 Mar 3 '15 at 13:01
  • Are you able to ping the gateway address? If not then how about pinging the gateway on its link local address? – Celada Mar 3 '15 at 13:06
