[Linphone-users] Linphone Stun issue

[pankaj anand]

hi,

 I am using linphone 3.2.0.99 build from sources on ubuntu 9.04

   I am using it behind a NAT and it is portRestrictedNat ( that i have tested with some other client). 

  

   somehow i found that the stun client is not behaving correctly, Instead of sending Ip address my Nat server and punched hole port no , it sends the local ( private ) ip addrss of my machine in SDP information. 

in logs i see that it says Symmetric nat detected for audio port. 

when I opened the code, I found that I sends a single message to the Stun Server and on the reply of that single message it can identify that what type of NAT is being used. 

please, Correct me if i am wrong. 

BTW what is the meaning of this line in the code :

*id=resp.msgHdr.tr_id.octet[0];

I don't understand the STUN protocols internal that is why couldn't understand this code. 

thanx in advance.
