I've got a freepbx server hosted behind a Cisco rv016 multi wan router. Trying to get extensions outside the network to register on the SIP server using a paid dyndns.org host, registered and updating on the rv016.
RV016 is x.x.x.23
Freepbx is x.x.x.150
I've created port forwards on 5060, 5061, 10000, and 20000.
I've also set firewall permissions on those ports, originating on WAN, going to x.x.x.150 to be all allowed.
When I use an external port checking tool, despite the settings above, it still says port 5060/5061 are closed.
Any suggestions are appreciated.
