Tina, Thanks for the comment.

The document is aiming at "minimal" set of requirements to make CGN transparent, I agree with that this could be helpful but I don't think this is a critical condition to make this I-D an RFC, isn't it ? > Moreover if port numbers are allocated to each CPE, what is the criteria for > allocation.

For example, if port is statically assigned, there is no need to have such record. So, again, I agree with that this is of course a clue to operate CGN better in certain environment, but still is not a critical, I think. So, how about we could create a document with such a hint for CGN operation seprately then let this I-D move forward now ? > Tina Best wishes, Shin Miyakawa
