Just to make sure I understand this correctly. Are you referring to virtual machines with "vps"?

ESXi only includes a firewall for it's own OS but not for the virtual machine networks. In order to monitor or block traffic, you need to implement your own firewall. Depending on your setup (single host or cluster) this can be a firewall VM (e.g. pfSense) with two uplinks, where one is connected to your network and the other on to a host-only vSwitch, together with the other - to be monitored - VMs.
