I'm new to this list and I have some questions concerning PANA and NAT
traversal. I've been browsing the mail archive and the current drafts
but I still feel uncertain about what the status is.

What I wonder is pretty straight-forward. Is PANA applicable in the
following two NAT scenarios:

1. NAT between PAA and EP

+----------+      +--------+         +----+   +-----+   +-----+     
| MN (PaC) |------| Router |---------| EP |---| NAT |---| PAA |
+----------+      +--------+         +----+   +-----+   +-----+
                   (One or
                         several)                                  .

     <=== Bootstrapped IPSec tunnel ===>

My understanding is that PANA should work in such a scenario (I've seen
some slide set from IETF62). Correct? Any issues?



2. NAT between PaC and EP

+----------+      +-----+     +--------+         +----+   +-----+     
| MN (PaC) |------| NAT |-----| Router |---------| EP |---| PAA |
+----------+      +-----+     +--------+         +----+   +-----+
                               (One or
                                      several)
.

       <======== Bootstrapped IPSec tunnel ========>

Whether this is also supported I feel unsure about. My understanding of
PANA details is not deep enough. Will PANA work here?


If someone could provide answers to my questions I'd really appreciate
it.

Best regards,

Bob Melander
