Hi,
I see From [RFC4861] the icmpv6 type 136 is still used for "Neighbor
Advertisement" messagges
136 Neighbor Advertisement [RFC4861]
You must modify your ipfw IPv6 rules... see this URL for all informations:
http://www.iana.org/assignments/icmpv6-parameters
Anyway the "echo request" message type is 128 and the "echo reply" message type
is 129.
Cheers
Raffaele

Just use ipfw the same like for IPv4, then since FreeBSD 6.x it
does also support IPv6. If you still have an older version of
FreeBSD, use ip6fw.

Hmm I have already used it as IPv4 firewall but it didn't work. are icmptypes
for ipv6 different from ipv4? i just want to block any echo request to my
computer from ipv6 network.
This is my Rule:
$cmd 00501 allow ipv6-icmp from $net to me in icmptypes 136 via $int
$cmd 00502 deny ipv6-icmp from any to me in icmptypes 136 via $int
