I have an Asterisk PBX running in my LAN which it has a mikrotik RB2011 and there was configured a NAT due the ISP gives me just one public IP.
I can make connection from an external network (the signaling is working fine due I open the port 5060) but the problem that I’m having is that the mikrotik is filtering the video. The softphone which is in the external network get the video streaming from the softphone which is in the LAN but not in the other way. So, making a reminder in the famous problem one way audio, I’m having one way video.
By the way I’m not having one way audio. The audio is working fine. So, I can’t discovery the ports. And between 2 softphone connected in the LAN the video streaming is fine!, so the firewall or the NAT is making something.
What ports should I open? udp protocol an ports (10000-200000)?
