I have posted to the ipsec-devel list and haven't gotten any responses. Also I

no results about the above setup. Is it even possible to tunnel ipv4 packet thru
an ipv6 ipsec tunnel?
AFAIK, No.
IPv4& IPv6 are different protocols so if you want to move IPv6
traffic over a IPv4 IPSEC tunnel you need to encapsulate the IPv6
payload within IPv4 packets. The reverse is also true of IPv4 over
IPv6.
This is why tunnel brokers like Freenet6& Teredo exist, you can't
push IPv6 traffic out across an IPv4 only network without tunneling.
Hi Drew,
Thanks for taking the time to respond. I understand they are different.
I want to
tunnel ipv4 in a ipv6 ipsec tunnel. Ipsec-tools lets me configure the
tunnels and
establishes the SAs but packets get dropped on the receiving side. I am
able to
create a 4in6 tunnel that ride inside a strict ipv6 ipsec tunnel so I
have a work around.
I am mainly trying to see if anyone has gotten what I described in my
initial post to work.
