Isolate VM in the same vmbr

[mmartincho]

Hi I need a hand with this issue.

I have a secondary vmbr where all my vm's are connected to.. it is a backup VLAN inside my proxmox. I would like to block visibility because all virtual machines are in the same network, ...like Private VLAN (in level 2 )
Can you gime me some advise?

Regars.!

If you want your VMs to be on separate LAN networks, either specify a different VLAN tag for each VM when configuring the network of the VM, or create multiple vmbr bridges, one per VM.

Can this be achieved by configuring vm firewall ? Configuring new net for each vm is quite overhead. I tried the firewall approach, but doesn't seem to have effect at all so far. If I change vm firewall from web gui, is the change immediate or I need to restart vm ?

Should be immediately. Maybe you forgot to enable the firewall on the network interfaces?

I have enabled it on datacenter, host and vm, don't know how to enable it on interface. I tried to make rules for particular interfaces but it didn't work

I found it, it's pretty obvious: see Firewall checkbox
