Hi again Richard et al, In the meanwhile I've figured out what was causing the issue. The problem was related to the way I had my iptables rules defined. I had :
-A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT and only after that -A INPUT -p udp -m udp --dport 16384:32768 -j RTPENGINE --id 0 -A INPUT -p udp -m udp --dport 49152:65535 -j RTPENGINE --id 0 I basically changed that to: ... -A INPUT -m state --state RELATED,ESTABLISHED -m udp -p udp --dport 16384:32768 -j RTPENGINE --id 0 -A INPUT -m state --state RELATED,ESTABLISHED -m udp -p udp --dport 49152:65535 -j RTPENGINE --id 0 -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT ... -A INPUT -p udp -m udp --dport 16384:32768 -j ACCEPT -A INPUT -p udp -m udp --dport 49152:65535 -j ACCEPT and now everything works as expected. Thanks for all the support anyway.
