In previous Neutron IPv6 team meeting, we discussed the requirement of providing NAT64 in OpenStack to facilitate the communication between IPv6 and IPv4 hosts. For example, from tenant IPv6 network to external traditional IPv4 network. I was suggested to initiate a discussion in ML to gather all forks thoughts.
I wonder if this is a fairly common requirement and what is the good way to add this possibility to OpenStack. Several ways we mentioned in previous sub-team meeting: 1. Add to current Neutron L3 This was also asked by Martinx in . 2. Run as service VM 3. Maybe even a new sub-project/project dedicated for address translation I also want to mention that NAT64 may not be the only requirement to communicate between IPv6 and IPv4 hosts. 6in4 tunneling and other methods are als candidates.  http://lists.openstack.org/pipermail/openstack-dev/2014-January/023265.html Your comments are appreciated!
