Re: Resolution of my discuss comments for draft-ietf-v6ops-nap-02.txt

for the record, this is only true of transport mode. tunnel mode works just fine in IPv4, and I have every reason to believe that it will continue to do so in IPv6. I use tunnel mode a lot, including at IETF meetings.

4.2 -2 does not oversell IPsec, it simply states the real situation.



I'm not going to hold your document based on the -03 text, but
I would still suggest the following edit:

       While IPsec might be available in IPv4
       implementations and works the same way, deployment in NAT
       environments either breaks the protocol or requires complex
       helper services with limited functionality or efficiency.

       While IPsec is commonly available in IPv4 implementations
       and can support NATs, NAT support has limitations and
       does not work in all situations. In addition, the use of IPsec
       with NATs consumes extra bandwidth for UDP encapsulation
       and keepalive overhead.
