32 packets hit the policer - double check your parameters please to make

They should all be usable. If something crashes, there is a bug

We are hopefully getting stable there. Anything on debian lenny
should be working with iptables 1.4.3; i expect at most "one last

I have sparse time this week - but i can help with Debian Lenny which
is what my laptop runs with some variable response latency.
