[SR-Users] rtpengine: Failed to open UDP control connection port

[David Cunningham]

Hi Alex and Richard,

After commenting out all the ip6tables there's still one warning about
'unknown option "--id"'. Evidently somewhere else it's trying to use
iptables for IPv6.

Anyway, we'll check if it's actually a problem. Thank you for your
suggestions!
