IPv6 provided through IPv4 VPN hair pinning on ASA not working.

spoke side: 

access-list V6 line 1 extended permit ip 2a02:xxx:3d02:2::/64 any6 (hitcnt=28) 0x0ca670f3

crypto map outside_map0 2 match address V6

traffic works for networks on the inside of the HUB ASA - but doing hair pinning and trying to reach internet does not work. 

ACL's: 

access-list outside line 1 extended permit ip 2a02:xxx:3d02:2::/64 any6 log debugging interval 300 (hitcnt=1(packet tracert))

access-list global_access line 5 extended permit ip 2a02:xxx:3d02:2::/64 any6 log debugging interval 300 (hitcnt=5(proberly also packet tracer))

 

packet tracert fails with: 

Phase: 8
Type: VPN
Subtype: ipsec-tunnel-flow
Result: DROP
Config:
Additional Information:

Result:
input-interface: outside
input-status: up
input-line-status: up
output-interface: outside
output-status: up
output-line-status: up
Action: drop
Drop-reason: (acl-drop) Flow is denied by configured rule

 

which is normal for the ASA - packet tracert does not understand VPN.... so im at a loss here - can the ASA do ipv6 hairpinning?

 

Does anyone know what im overlooking? :-)
