Hello!
I have a quite simple setup with three nodes. All of them have two network interfaces which are all connected to the same switch.
Moreover I have a /28-IPv4 and a /64-IPv6 subnet.
All network-configuration were done via proxmox webinterface - I didn't change anything in a file.
The `/etc/network/interfaces` of one of the hosts (look all equal, just other IPs of the subnets):
One the hosts everything works fine. IPv4 and IPv6.
Now I create a minimal Debian 8 LXC on the webinterface and give it a IPv4 and IPv6 address, which ends up in this /etc/network/interfaces:
But on the container IPv6-pings always answer "Destination unreachable: Address unreachable". `ifconfig` and `route -6` look correct.
DNS settings are not modified on the container (so it uses the hosts ones) and firewall is disabled.
Where is my mistake?

# Please do NOT modify this file directly, unless you know what

# If you want to manage part of the network configuration manually,
# please utilize the 'source' or 'source-directory' directives to do
# so.
# PVE will preserve these directives, but will NOT its network
# configuration from sourced files, so do not attempt to move any of
# the PVE managed interfaces into external files!
