traceroute & ping fail
I think it's my firewall blocking them going _out_ because when I take the
firewall offline both ping and traceroute work fine. Ping works on localhost,
though traceroute does not when the firewall is up. Unfortunetly I am too new
at both debian and firewalling to know where I went wrong. I'm trying to set
it up so I can ping and traceroute to other boxes but other 'bad' boxes can't
do it to me. What information can I follow this msg up with that will be
helpful?
I call the firewall from /etc/rc2.d/S90firewall_up which is just a sym link to
/etc/init.d/firewall_up.
On a side note, when I added the logging line:
$IPT -A Firewall -j LOG --log-level info --log-prefix "Firewall:"
It produces a TON of the following as fast as it can put them in the log file.
How do I read this and even more importantly how can I make it log the "rejects"
properly so that I can actually catch people trying to scan the box etc.

If it would help I can attach the actual firewall script.
