→Building a Firewall With Firewalld on VM3
*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. Use the same log message as on your other machines.
**Block all pings from the host.
**Allow pings from your other VMs.
