Hello.
I have problem with double vlan tagging setup. I want to split 'trunk' link to different VMs using 802.1ad tag, and split 802.1q tags on the VM (on the guest machines).
My /etc/network/interfaces file:
Code:
auto lo
iface lo inet loopback

iface enp0s3 inet manual

auto enp0s8
iface enp0s8 inet manual
        post-up ip link add link enp0s8 enp0s8.104 type vlan proto 802.1ad id 104
        post-up ip link set enp0s8.104 up

auto enp0s8.104
iface enp0s8.104 inet manual

auto vmbr0
iface vmbr0 inet static
        address  192.168.0.200
        netmask  255.255.255.0
        gateway  192.168.0.1
        bridge-ports enp0s3
        bridge-stp off
        bridge-fd 0

auto vmbr1
iface vmbr1 inet static
        address  192.168.104.200
        netmask  255.255.255.0
        bridge-ports enp0s8.104
        bridge-stp off
        bridge-fd 0
        bridge-vlan-aware yes
        bridge-vids 2-4094
Network interfaces looks good:

But when i trying to ping 192.168.104.200 (or attached to bridge VPC), I see only ARP, no ICMP:

I disabled firewall on GUI. This config works when I replaced proxmox host by host with raspbian OS.
Why this don't work here?
