When it comes to streaming with an RTMP firewall, most people don’t need to open any ports and can start to stream live video right away.
However, if you are having trouble and believe you need a port open for the RTMP firewall, 1935 should be the key.
RTMP Default Port
This is the default port for RTMP (Real Time Messaging Protocol) encoding. With an RTMP encoder, our service is set up to try to use ports 80 or 443 if 1935 isn’t open, which is why most should be fine.
For more technical information about the ports, Dacast can use TCP 1935, TCP 443 RTMP, or TCP 443 80.
