Re: [Hipsec] I-D Action: draft-ietf-hip-native-nat-traversal-23.txt

[Miika Komu <[e-mail]>]

FYI,

the major changes in this version are:

4.12.3. Handling Conflicting SPI Values
* a new way to handle conflicting SPIs by utilizing multiple relayed 
candidates
* this changed affected also sections 4.1, 4.2, 4.12.1, 5.13.

4.9.  Mobility Handover Procedure:
* the exchange of locators must be three way in order to avoid replay 
attacks
* clarified double jump

Minor changes:

4.7.1.  Minimal NAT Traversal Support:
* clarified how mobility is supposed to work in this case

4.10. NAT Keepalives:
* the Data Relay Client and Data Relay Server MUST employ only HIP 
NOTIFY packets in order to keep the server reflexive candidates alive

5.10. Notify Packet Types:
* A new error value: SERVER_REFLEXIVE_CANDIDATE_ALLOCATION_FAILED

5.13.  PEER_PERMISSION Parameter
* Additional port and address added because multiple server reflexive 
candidates can be leased

6.2. Opportunistic Mode
* Clarified that anycast and multicast are out of scope

7.  IANA Considerations
* Error values are listed also here

Appendix D.  Multihoming Considerations:
* new section on future compatibility with possible multihoming extensions

* Some minor clarifications here and there
