Clarifying VM3 instructions because firewalld doesn't work on MAC addresses.
*Remove all services except ssh from the work zone (effectively blocking all incoming traffic except ssh).
*Use the firewallcmd rich rules to make the following changes (very similar to what you did on VM 1):
**Log and block all ssh attempts from your host's ip address. Use the same log message as on your other machines.**Block all pings from the host's ip address.
**Allow pings from your other VMs.
*Unlike iptables where you save your current state in bulk, firewalld requires you to save each change independently.
