[Serusers] NAT type detection

Hello,
I've been using Asus WL-500G as NAT/Router device for my testing 
purposes with SER.
I implemented MyStun server which is running on the same OS as SER on 
192.168.1.50.
I also have two IP addresses on the server which are 192.168.1.50-51 for 
MyStun functionality.
When I start MyStun it listens on default ports 3478 an 3479.
UA behind the NAT is Xlite so the STUN implemetation of this softphone 
should be ok.

Question 1:
Where should I be able to determine/see what type of NAT I'm behind with 
X-lite?

I'm trying to combine NAThelper/RTPproxy with STUN and use STUN if there 
is no symmetric NAT.

Question 2: Could you advice me what tools I should use for debugging 
functionality of STUN, please?

Hopefully, everything is clear.

Ladislav
