A lot of our clients can’t connect to 1935 port, but have an option to use RTMP, so we need to provide direct (not-tunneling) channel over port 80. How can we do it?

I’ve found a [discussion](https://www.wowza.com/forums/showthread.php?4106-Default-to-port-80-after-1935)

Also take a look at:

[https://www.wowza.com/docs/how-to-install-and-configure-wowza-streaming-engine#addtionalPorts](https://www.wowza.com/docs/how-to-install-and-configure-wowza-streaming-engine#addtionalPorts)

After you re-start Wowza, check the startup lines in the access log to ensure that Wowza was able to bind to that port. If you have a web server running on the same machine it won’t bind to the same IP:Port.
