Well, if your provider uses one of those whateverbox they're so fond to 
use, it probably has two modes :
1. a transparent mode where everything gets to your box, in which case 
you don't have NAT (but still need to open the right ports) ;
2. a router mode where you only have a private ip, and the whatever box 
acts as a router, in which case you have NAT.

I don't understand why you have two lines of ports, but it looks sane, 
at least for the TCP range.

But you also need to open the listen port and the RTP range, as 
described in the section 7 of the FAQ : remember netmeeting doesn't do 
H.245 tunneling.
