Issue with VLAN configuration

Hi,
I have a issue configuring my network.
My lxc and vms from vlan 30,40 and 70 are getting an ip via dhcp from my opensense if I set the correct tag in the settings (vmbr0 and vlan tag). However all lxc or vm assigned to vlan 20 and vmbr0 won‘t get anything.

Here is my network config:

Code:
auto lo
iface lo inet loopback
 
auto eno1
iface eno1 inet manual
 
auto eno2
iface eno2 inet manual
 
# Bonding configuration
auto bond1
iface bond1 inet manual
    bond-slaves eno1 eno2
    bond-miimon 100
    bond-mode 802.3ad
    bond-xmit-hash-policy layer3+4
 
# VLAN-aware bridge that handles multiple VLANs for VMs
auto vmbr0
iface vmbr0 inet manual
    bridge-ports bond1
    bridge-stp off
    bridge-fd 0
    bridge-vlan-aware yes
    bridge-vids 2-4094
 
# VLAN 20 bridge for Proxmox host IP
auto bond1.20
iface bond1.20 inet manual
 
auto vmbr1
iface vmbr1 inet static
    address 10.0.20.100/24
    gateway 10.0.20.1
    bridge-ports bond1.20
    bridge-stp off
    bridge-fd 0
    bridge-vids 2-4094



Is it possible that I did a mistake here and my bond1.20 or vmbr1 is blocking vlan 20 on vmbr0? My host (on vlan 20) is able to connect and ping. I tried to set a static ip, but even then: no connection possible. On the opnsense-side are all vlans configured the same.

Thanks for and help in advance.
