I was trying to write up an iptables script last night and managed to
get it work, or so I thought.
When I run it, the interface just dies.
It's still configured and "up", but any kind of traffic sent to it is
ignored. I even added lines like:
iptables -A INPUT -i $IFACE -j LOG
and I don't get any logging in /var/log/syslog
What's worse, if I remove all the rules and reset the default policy to
ACCEPT it doesn't get any better.
Is there some "issue" between iptables and the 2.6 kernel I should know
Is there any way I might be able to trouble shoot this effectively?
Right now my only option is to reboot the machine entirely to get it
working again. This can't be right.
