freebsd-ipfw Digest, Vol 270, Issue 1

[Raffaele De Lorenzo]

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
