Hello,

Some comments on your draft which I believe is interesting.

Most of your tests are subscriber initiated connections which results in
Internet (I) ->subscriber (S) traffic over TCP/UDP. We all know this works
well with CGN. The interesting cases are I/S<->S for gratuitous
connections. In that sense, some comments below.

Is on-line gaming with consoles popular in China? PS3, XBOX, Nintendo?

People do not seed torrents in China? That is very popular in other parts
of the world. 

I would like to understand how the CGN was configured. Were mappings APP
enabled? EIM & EIF? Hairpinning enabled? This, of course is specially
interesting on the I/S<->S scenarios.

As far a VPN goes, the interesting ones from CGN perspective are IPsec
(not over UDP) and PPTP.

Thanks,

- RP
