I'm trying to setup a Freepbx VOIP system. It will work fine depending on what ports are randomly selected. If the traffic occurs on port between 5000-20000 it seems fine. Anything above that doesn't work and gets blocked.
I have created a port forward rule to allow incoming traffic from the voip.ms server on all ports 10000-65535 UDP yet it still gets blocked.

see attached screenshot of  rules and log.
