Thanks very much.
Actually protocol ICMP does not seem to be allowed 
in the Firewall on my Billion 5200S RC.
But I see that this protocol is allowed in "Access Management".
I just tried adding a rule with ICMP protocol,
but it seemed to have a bad effect!
(I was cut off from the outside world.)
I'm sure this is the right way to go, anyway,
so I'll continue my experiments.

Thanks again.
