#257 — unable to ping/ssh w/ fedora

Hi all,

What's going on is I can't ping or ssh from the remote to the local
but I can ping/ssh from the local.  My system has a cable ISP and
a wireless router. I've already tried unplugging the cable and the
router and restarting, and I've tried shutting off the firewall.
What else could be the problem? The OS is fedora.

You didn't state your problem clearly enough. What is a "remote" and a
"local"? Where did you ping *to*?  What messages did you get, if any?
What does it mean that your "system has a cable ISP"?  
And so on.

This sounds like normal behavior for typical Internet access through
NAT. What makes you think you have a problem?

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.
