Hello! I’ve a problem with looping ACK, when using topology_hiding(«U») on Amazon EC2 server with Elastic IP. All works fine without topology_hiding.
I’ve set advertised_address=«54.54.54.54» (it;s example of my Elastic IP address) option in config and have no other special functions like «rewrite host()» and others in config. And now, when I receive ACK - it’s looping (some headers are cuted): U 2014/08/21 10:18:29.040856 62.62.62.62:5060 -> 10.0.0.196:5070 ACK sip:77777777777@54.54.54.54:5070;did=d99.910e2214 SIP/2.0.
