Multiple bridges problem

[Katoz96]

Hello, in my server I have 2 ethernet ports and I want to use one to move a container in a different DMZ subnet. I created a new bridge with only the port I need and I assigned it to a virtual machine to test the firewall rules I created, everything works as it should but there are two problems:

If I assign the bridge to a container the rest of the containers receive an IP address inside the DMZ even if the bridge hasn't been assigned to them and they bounce between the 2 subnets.

If I assign the bridge to a VM it bounce between the 2 subnets, the other VMs don't seem to have the same problems as the containers.

I can't understand if it's a Proxmox problem or if I made a mistake in configuring the firewall. Can anyone help me?

Thanks

Hi,

Linux bridges are isolated. So I guess you have a routing problem in the VM or on the host.
But to say this for sure your configuration is required.
Without nobody can help you.
