Sir,

=20

This is a follow-up from my previous email "Racoon2 Problem with =
Dual-stack
Configuration on FreeBSD". As what I have tested in IPv6 SAs on my =
FreeBSD 6.0
systems, I am using upper_layer_protocols "any" which covers TCP, UDP =
and
ICMPv6. When I try selecting protocols such as TCP and UDP only and run =
the SPMD
and IKED daemons, IPSec just runs fine. I've suspected the Neighbor =
Discovery
Process since its using ICMPv6 for Neighbor Solicitation and Neighbor
Advertisement process whenever IPv6 nodes communicate with each other in =
a
certain link for transport mode that when you apply IPSec on this =
particular
communication, then two nodes got lost because ICMPv6 is already =
encapsulated.
In IPv4, since is doesn't use Neighbor Discovery Process then upper =
layer
protocols "any" can be specified without any problem. That's why when =
booting up
on FreeBSD systems and apply directly with SPMD and IKED, IPv6 nodes =
cannot
received/reply ICMPv6 messages. Only IPv4 is executing normal. Just =
correct me
if I'm wrong with my suspicion. Thank you.
