Hello!
For the first time I try to use IPv6 with Proxmox (I don't have experience with IPv6 at all).

My problem is related to fact I can ping ipv6.google.com from main node but I can't ping from LXC container. When I try to ping from container nothing happens, ping command freezes.
Thank you!

/etc/network/interfaces
Code:
auto vmbr0
iface vmbr0 inet static
    address X.XXX.XXX.XXX/24
    gateway 5.183.171.1
    bridge-ports ens2f0
    bridge-stp off
    bridge-fd 0

iface vmbr0 inet6 static
    address 2001:470:22c4::1/48

auto vmbr2
iface vmbr2 inet static
    address 10.0.0.1/24
    bridge-ports none
    bridge-stp off
    bridge-fd 0
    mtu 1500

iface vmbr2 inet6 static
    address 2001:470:22c4:ffff:ffff:ffff:ffff:ffff/48

auto he-ipv6
iface he-ipv6 inet6 tunnel
    mode sit
    address 2001:470:1f1a:574::2/64
    gateway 2001:470:1f1a:574::1
    endpoint 216.66.87.14
    local X.XXX.XXX.XXX
    ttl 255
    post-up echo 1 > /proc/sys/net/ipv6/conf/all/forwarding

VM configuration:

EDIT: Now I realised that I try to use same interface for NAT IPv4 and public IPv6. It is possible?
