This issue may be old for you, but it is brand new for me and I need some help to open the ports.
For port 1935, udp or tcp, input or output;
For port 1936, udp or tcp, input or output;
For port 5080, udp or tcp, input or output;
I guess for the 1935 and 1936, one must be as input and the other as output. Not sure for port 5080.
Thanks.
