Hello, might be just a typing mistake, but:
rtpproxy -A "private ip" -F -l "local ip" -m 10000 -M 20000 -s udp:*:7722 -d INFO says that -A is private ip, it should be public IP. Then, towards asterisk, is it everything on a private network, or does it go again through some FW with public ip and port forwarding?
