I assume your "HW firewall" protects you to the outside. Of
course it should allow SSH connections from the outside to
the "tao" box _if_ you want it that way.
But I was thinking about the firewall run by the Fedora OS
that might block SSH connections to "tao", no matter from
where they come, just as if you would have set up FreeBSD's
ipfw with the default to deny connections: without explicitely
enabling SSH connections the server cannot be reached, no
matter if it's running.

Check if the Techotopia article matches your version of Fedora.
It shows how to install and enable the SSH server and also
mentions the "built-in" firewall that has to be configured
to allow connections to that server.
