No, we don't ship with the firewall configured by default.

That is "normal".

Nope. We ship with no ports open by default. So you had to actively
install an ssh server, at which point you can make the decision about
whether to firewall it or not.

they have built in firewalls running by default. "

That's questionable. We have a firewall "on" by default in that it's
based on iptables built into the kernel, but nothing is configured as
blocked by default, because we don't ship any open ports by default as
I said.
