Good Morning, I need to set a VOIP architecture with natted users. And I'm trying to prevent bottleneck (with a rtpproxy architecture) and I have a full access to the nat server (debian box / iptables MASQUERADE NAT). So, I've compiled nf_nat_sip / nf_conntrack_sip modules that changed the received RTP stream IP with the public one of my nat box. So the RTP stream is arriving to the natbox! Do you have any idea of a solution to forward RTP streams to the end user Best Regards, Marc
