sysAttrPacketFilterAllowImportantIcmp

This option causes the packet filter to automatically 
accept a number of important ICMP types without requiring 
the addition of a rule to handle them. Acceptance of ICMP 
traffic by this option occurs prior to rule list evaluation, 
making it impossible to override the behavior of this option 
with a rule. The types of ICMP packets accepted by this 
option include:
UNREACH (3) - all types 
SOURCEQUENCH (4) 
REDIRECT (5) - all types 
TIMEXCEED (11) - all types 
This option is enabled by default.
