You need to use a NAT on your router to route external connections to your internal server. We have an article on network troubleshooting. [https://www.wowza.com/docs/how-to-troubleshoot-wowza-streaming-engine-installation#network](https://www.wowza.com/docs/how-to-troubleshoot-wowza-streaming-engine-installation#network) From the article. 1. If you’re trying to access Wowza Streaming Engine on a different network, check to make sure that the specified ports are open on the server’s public IP address or public domain host name. You can check the ports by using a network sniffer program such as Wireshark. 2. Make sure you’ve configured any port forwarding or NAT rules correctly on your router or switch. You can check port forwarding and NAT rules by using a network sniffer program such as Wireshark.
