[Serusers] send_rtpp_command error in nat configuration

Hello, This is partially linked to my post this morning regarding having no audio between clients on different nats. I have spent the whole day trying different configurations and at this stage I think the reason its not working is coming down to the rtp errors (ERROR: send_rtpp_command etc). My problem as such is exactly the same detailed in the below thread (see below) which I found in the archives. However whilst suggestions were made regarding this problems (check that the versions are up to date and that you have sufficient permissions to rtp.sock etc)...no actual definitive solution was given. I have tried all the recommendations and none work. My deadline is looming so if someone (anybody) who has experience this problem and solved it, or just someone who has ideas, could give me pointers, I would be VERY appreciative. Kindest Regards, Aisling. Hello, I am have having difficulty getting rtpproxy and ser to work together correctly. Each time I start ser (after first starting rtpproxy) I get the following errors: textops - initializing stateless - initializing Maxfwd module- initializing 0(0) INFO: udp_init: SO_RCVBUF is initially 42080 0(0) INFO: udp_init: SO_RCVBUF is finally 231808 0(0) INFO: udp_init: SO_RCVBUF is initially 42080 0(0) INFO: udp_init: SO_RCVBUF is finally 231808 5(2195) 4(2194) 2(2192) 1(2191) ERROR: send_rtpp_command: can't read reply from a RTP proxy ERROR: send_rtpp_command: can't read reply from a RTP proxy 13(2203) 14(2204) 15(2205) 16(2206) 17(2207) ERROR: send_rtpp_command: can't read reply from a RTP proxy 3(2193) ERROR: send_rtpp_command: can't read reply from a RTP proxy 5(2195) 4(2194) ERROR: send_rtpp_command: can't connect to RTP proxy <rest of errors removed; more of the same> Looking through the list I thought it was an incorrect rtpproxy version and downloaded and installed the stable 0.8.14 ser version and latest rtpproxy from CVS. But I still see the same errors. I can see the rtpproxy process running and rtpproxy.sock is present. Currently I have ser 0.8.14 and rtpproxy 1.21 2004/08/13 running on freebsd 4.10. Aside from these errors the calls set up fine but with no audio. I have been searching through the list and google for a couple of days but still seem to be missing something. Any thoughts on what I should try next?
