Hi Caceres,

not yet... A long time ago Marty released a beta (or alpha) 
version of snort supporting IPv6. But it was more a framework
than an usable system.

The actual version of snort is only IPv4 capable, IPv6 packets
are only counted.

This are IPv4 ICMP messages regarding to an original IPv6 packet. So
this works for snort...
