Hi have a bunch of VLANs and bunch of VMs running on Proxmox. On Proxmox host I have a Linux bridge and it's "VLAN aware".

Funny thing is, with Windows guests and VirtIO drivers installed everything works. With Ubuntu guests that I setup their static IPs using `netplan` inter-VLAN communication doesn't work. Can't get any of the Ubuntu guests "see" each other between the VLANs. Any suggestions? What I might be missing?
