Hi,

i have one testing PVE in my homelab, and one in Datacenter. Since one Week every new VLAN i tag inside the VM-Configuration will not work.
I only use my vmbr0 without VLANs Configured. In Datacenter it is a Standalone Server so there is no Switchconfiguration.

Node:

auto lo
iface lo inet loopback

iface lo inet6 loopback

iface enp4s0 inet manual

auto vmbr0
iface vmbr0 inet static
address x.x.x.x/26
gateway x.x.x.x
bridge-ports enp4s0
bridge-stp off
bridge-fd 0
hwaddress x


VM tag inside configurator.

Any Idea?



Problem for example: 2 VMs with new tag 51 on Networkcard cannot communicate.

Old VMs with tag 5 still working.

New VM with tag 5 can communicate
