From the server-side firewall's standpoint, to support passive mode FTP the following communication channels need to be opened: 1  FTP server's port 21 from anywhere (Client initiates connection)  FTP server's port 21 to ports > 1023 (Server responds to client's control port)
This behavior can prevent communication over RTMP even if port 1935 is open. Consult the documentation for the firewall to determine how to configure it to allow RTMP traffic. To use RTMP and RTMFP, firewalls between the server and clients must allow inbound and outbound traffic on port 1935. If you cannot configure the firewall to allow traffic on port 1935, configure the server to use a different port.
