When setting up PF I found the recommendation to use the following rule to allow ICMP to pass. # macros icmp_types="echoreq" # filter rules pass in inet proto icmp all icmp-type $icmp_types keep state I do not understand why this is necessary! Will someone Please explain to me why it's necessary if I must have it, or if I can delete that rule. Thanks /Leslie
