Results on draft-jennings-midcom-stun-results-01.txt

Hi all,

It's useful to have some NAT type results on 
draft-jennings-midcom-stun-results-01.txt, to know what's out there on 
the market.

I've read that the NAT type is discovered using the WinStun utility, is 
it the case?

I have performed ethereal capture on the STUN requests from the WinStun 
utility and found that it is not strictly following the NAT discovery 
as outlined in the RFC 3489. Therefore, the results may not be the 
same, if someone performs the NAT discovery following RFC 3489.

I also have a question on the NAT discovery in RFC 3489. For the NAT 
discovery procedure, should all STUN requests be sent from the same 
source port?

Thank you very much.

Best Regards,
Tony Yat-Tung Cheung
