>Description:
sbin/ip6fw has a type mismatch (unsigned in struct declaration vs.
u_long as parameter type) that leads to errors in the rule parser for
icmp type codes. This is a problem on all 64-bit platforms, where
sizeof(int) != sizeof(long)
>How-To-Repeat:
falcon# ip6fw add allow ipv6-icmp from any to any icmptype 128,129
00000 allow ipv6-icmp from any to any icmptype
>Fix:
