I apologize in advance for any silly and seemingly simple questions, but I am new to this. I have virtual machines with static IP addresses connected to vmbr0. The MAC filter option is enabled in the firewall for all machines, and I have also created rules for each VM that allow sending/receiving packets only to the permitted address. My task is to ensure that the machines do not see each other's traffic, and I checked with tcpdump and indeed see nothing except ARP packets. Do I need to take any further actions to segment the network, or is it already safe in the context that VM1 cannot influence VM2 in any way ? (in the context that they both use vmbr0)
