Thanks very much. I knew what ICMP packets were, but I was asking about the
use of this packets between the members of a cluster (about the use of ICMP
packets in that case). I wanted to know the need of this packets because I
had to add a specific rule to permit this traffic in order to avoid dropped
packets.
Thanks in advance.
