Well... I've tried it from a laptop behind an iptables firewall to a 
stand alone host on the net and it does not work and I've tried it from 
the firewall itself to the same stand alone host and it does not work 
there either. I was hoping it would work from the laptop but it looks to 
me as though it won't work from anywhere. A thorugh (2 day long) search 
of the net suggests there are issues with Cipe and iptables.
