Hello all again
I have to apologise for the letter I wrote earlier. As I walked
to the bus-stop on my way to work I realised what I had done
Near the very top of the fw is the following:
$IPTABLES -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
Thus anything that is part of a connection will be accepted. The first
packet will hit the rule:
$IPT -A INPUT -p icmp -s 0/0 --icmp-type 8 -m limit --limit 3/minute -j LOG --log-prefix "ping"
but all the following packets will never get to that rule but will
be accepted because they are part of an 'ESTABLISHED' connection.
