On my server, I have the option of using either Rtpengine for NAT traversal or pure TURN without rtpengine.

Rtpengine has the obvious plus that it only needs 1 public IP, while TURN (with STUN) will need 2 public IPs, although that's not a problem in my case.

Having said that, I'd like to take advantage of the huge experience that users of this list have in real world deployments. in your experience, which option is more reliable in a real world deployment?

Cheers,

Peter
