[Users] NAT issue with devel version

Hello, I am testing 1.2.0-pre8-notls version running with mediaproxy and I have noticed someting very strange: When a client is behind nat it never connects to the mediaproxy for the RTP exchange. I have checked the sip traces, the media IP translation is done correctly in the SDP body. My setup has already worked some time ago (with devel version) and I haven't made big changes since. Were there changes on the way nat is handled that I have missed ? I tried to set the "received_avp" and "nat_bflag" params but this don't help. If somebody have a hint for me, I would be glad to hear it. Thank you ! -- Regards, -vma .
