Port forwarding is the process of configuring a router to make a network device that is connected to it accessible to other computers and network devices from outside of the local network. Port forwarding uses an IP address plus port number to route network requests to specific devices. TelVue recommends that configurations of port forwarding rules in your router’s firewall should only be done by IT personnel with knowledge of proper configurations.
To get the most out of your TelVue HyperCaster, consider implementing the following port forwarding rules:
| Port | Protocol Type | Service Name | Use | Restrictions |
| 22 | TCP | SSH | Remote access for TelVue Tech Support | Restricted to 8.39.99.1 |
| 80 | TCP | HTTP | Remote access to user interface | None* |
| 443 | TCP | HTTPS | Remote access for TelVue Tech Support | Restricted to 8.39.99.1 |
| 1935 | TCP/UDP | RTMP | Allow streaming of RTMP sources | None* |
*If possible, limit to known IP addresses that will be accessing
Remote Access to the HyperCaster User Interface
For remote HTTP access to your HyperCaster’s user interface from outside your network, a port on your firewall (typically port 80, or if that is used for another HTTP service, another port) must forward to port 80 on your HyperCaster’s management IP address. This will enable users to perform tasks, such as starting and stopping live events, scheduling of content, editing and triggering overlays, as well as the use of the Emergency Notification Console by authorized emergency users.
Playing & Recording Live RTMP Push Streams
If you have an application or encoder outside your network that is capable of generating an RTMP Push stream, such as a NewTek TriCaster, Sony Anycast, LiveU, Teradek, Wirecast, or TelVue TeleCast 2, the HyperCaster can decode this stream, enabling you to go live essentially from any location. In order for the RTMP stream being pushed to reach the HyperCaster, the port receiving the stream on your firewall must forward to port 1935 (UDP/TCP) on your HyperCaster’s management IP address.
Your HyperCaster can do RTMP Pull from a Content Distribution Network (CDN) without a port forwarding rule to port 1935.
Secure Remote Access for TelVue Technical Support
To get the most out of your TelVue Care service contract and allow TelVue to have full diagnostic and support access, a port on your firewall must forward to port 22 on your HyperCaster’s management IP address. For security, this should be restricted to only allow access to the TelVue Network Operations Center (NOC) at IP address 8.39.99.1.
Intelligent Platform Management Interface (IPMI), when configured along with SSH access, allows TelVue to provide the highest level of technical support. To enable IPMI access to the HyperCaster, a port on your firewall must forward to port 443 on your HyperCaster’s IPMI IP address and a network cable must be connected to the HyperCaster’s IPMI port. For security, this should be restricted to only allow access to the TelVue Network Operations Center (NOC) at IP address 8.39.99.1.
