Lorenzo

You have a very valid point about documenting the source-destination routing on the same 'foot' as NPT6.

And of course, we are in agreement on NPT6 breaking applications (probably less though than NAPT)

-       Having the internal network up when DHCP-PD is failing because WAN link is down (at least they keep ULA and loose only their GUA), this should be mentioned in our I-D

I think we all agree that ULA + GUA is an accepted use case that should go into this document as well. Are you saying that ULA-only should to into this document as well? I don't think there is consensus on that.

-       Having a simple and cheap way to do multi-homing, search about multi-homing, load-balancing, ... for SMB and those boxes uses RFC 1918 inside + NAT towards two ISP or two links (xDSL & 4G)... Not all SMB will get a PI space and will run BGP.

That's why we're working on source+destination based routing, which is a much better solution than anything involving translation. and since this is an IETF document, I think it should document src+dst routing (which is gaining consensus and has a lot of work going on around it in various working groups) over ULA-only, whose only reason for existence is "it's similar to what we do in IPv4, which we all hate".

-éric (and YES I dislike NAPT for breaking apps, and making security worse)

NPTv6 breaks apps too. For example, it will break anything using libjingle (e.g., Google video chat).
