I am seeing thousands of IPS blocked attacks (rule 460 and 461) generated by 2001:470:b:*::1, which is the address of utm. The destinations are my computers also using ipv6. These blocked attacks constitute 98% of the blocked attacks. This was reported in the network protection group in this thread. Is this a bug in the rules or is utm generating bad ICMP packets? (The rules are both broken together, at least there are equal numbers of both attacks.)
