Great - thanks!

The object had an address family field in the past. However, this was kicked out as of WG consensus. All NAT stuff in the NATFW NSLP was IPv6 NAT capable in the past, but we removed this, as this type of NAT was considered very, very evil.

Hope my answer above addresses your concern.

Changing back would require IMHO a) an IETF consensus that we allow IPv6 NAT in general and b) WG consensus to bring the IPv6 NAT functionality back to the NSLP.

Thanks,
