but when run rtpproxy in bridge mode why it doesn't update the packet to proper NAT hole?
Due to the very nature of the bringing mode - it's assumed that UAs on each side of bridge can talk to the bridge directly, so that no NAT traversal is necessary. You can disable this by comenting out the following two lines in main.c and recompiling rtpproxy:
[...] if (bmode != 0) asymmetric = 1; [...]

Can it be solve by any method ?
Thanks Jimmy

The old rtpproxy (1.1.1.1) has to wait for at least one packet from each client. For the new version of rtpproxy it depends on the configuration, i.e. if the rtpproxy is symmetric on both ends or only on one end.
The default behaviour is to start relaying immediately to the port specified in the SDP, but once the firt packet from UA has been received check that actual source port match and update internal session data if it does not so that all subsequent packets will be relayed to the proper "NAT hole".

Hi all: in http://www.voip-info.org/tiki-index.php?page=Portaone%20rtpproxy is says rtpprxoy will waits for receiving at least one UDP packet from each of two parties participating in the call Once suc packet is received, the proxy fills one of two ip:port structures associated with each call with source ip:port of that packet and when both structures are filled in, the proxy starts relaying UDP packets between parties; is it always do so ? Cause when I have try rtpproxy with nathelper , but when i trace the etherreal log rtpproxy's behavior seems not waits for receiving at least one UDP packet from each of two parties after when receive only one part of the UA , rtpproxy directly transfering the rtp packet to another UA
Can any tell me will rtpproxy wait for when both UA's first packet has received then start relay it ?
Or it's behavior is really the same as the page said ? (http://www.voip-info.org/tiki-index.php?page=Portaone%20rtpproxy)
