Hi.

I try to test the VM firewall between two guest OSs (Linux) installed on Proxmox.

Two Guest VMs A and B

- The network interface of the VM has been configured with the DHCP and NAT configured Bridged interface (vmbr10) of Proxmox HOST.

In the above statement;

- VM A tried to set the VM firewall(Drop or Reject) to control traffic between A and B, but it does not work.

- After I was set the 'inbound drop' of vm interface (net0) of VM A and trying ping or ssh from VM B to VM A, but the connection is possible.

Please let me know how to set up a firewall between VMs using Proxmox.
