It is defined as array of 'unsgined' in /usr/include/netinet6/ip6_fw.h, but in the prototype of fill_icmptypes it is defined as array of 'u_long'. In amd64 platform, u_long != unsigned. It causes wrong icmp types to pass to ip6fw kernel module. >How-To-Repeat: run the following command in amd64 platform: # ip6fw add 10 allow ipv6-icmp from any to any icmptypes 63 00010 allow ipv6-icmp from any to any icmptype 95,96,97,98,99,100,101,102,103,104,105,106,107,108,109,110,111,112,113,114,115,116,117,118,119,120,121,122,123,124,125,126,127 >Fix: Apply attached patch. >Release-Note: >Audit-Trail: >Unformatted:
