Why enable FirewallD

Also, a more experienced user may already is used to set up firewall rules from some saved rules, the majority of users still forget to secure the system after the initial installation.

I do not quite understand the issue.
Because the router has a firewall, why should you use a second one on the client?

What if you are a laptop user jumping into different networks regularly; Having applications installed that open ports on your network interfaces ? What if you are a desktop user having devices in your network that cannot be trusted ?

Imho, having a firewall installed/enabled (blocking incoming traffic by default) makes sense.

Although I already see forum threads coming like samba server not working, can not connect to ssh on my machine :wink:
