I have setup a VLAN Bridge with Proxmox. I have multiple VM's as well as Physical hosts in my network. The physical hosts can communicate with the VM's over VLAN but my guest O/S's cannot communicate across VLANs to each other. I suspect this is because in the bridge setup Guest to Guest communication never reaches the physical switch. Is this a Proxmox Firewall ACL issue or does the bridge need to be configured differently?

Hi,
is your connection to the switch setup as a VLAN trunk? Did you set your bridge to "VLAN aware"? You can also try tcpdump on the outgoing host interface to see if the packages get send to the switch [1]:
