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.

<br>
Thanks for taking the time to respond. I understand they are different.
I want to<br>
tunnel ipv4 in a ipv6 ipsec tunnel. Ipsec-tools lets me configure the
tunnels and<br>
establishes the SAs but packets get dropped on the receiving side. I am
able to<br>
create a 4in6 tunnel that ride inside a strict ipv6 ipsec tunnel so I
have a work around.<br>
<br>
I am mainly trying to see if anyone has gotten what I described in my
initial post to work.<br>
