How is your router configured? If you want to ssh into the Fedora box from 
the Internet you will have to port forward the ssh port to the box. The 
standard port for ssh is 22, however unless you have a compelling reason 
for using the standard port you should move ssh to a high port. The reason 
for moving it is to hide from port scanners, with the standard port you 
will see about one break in attempt a day, if you pick a non-standard port 
you won't experience any break in attempts unless you are a high value 
target.

Pings are usually handled by the router. Typically ICMP responses are 
disabled which is why you can't ping your network, if you want to be able 
to ping your router you must enable ICMP responses, however be advised 
that if you do that you are letting the scumbags know that you exist.
