Information Tightrope needs to set up Cablecast Reflect

Applies to

• Cablecast 5.3.0

Answer

To setup your Cablecast Reflect account, Tightrope needs the public IP address for each Pro, ProVOD, Live330, and SX Live server in your system. These addresses need to be available from the public internet. Access to these machines can be achieved either by port forwarding or network address translation (NAT). See below for additional information.

Additional Information

Cablecast Reflect intelligently caches popular content and aggregates multiple requests for the same content. This enables your Cablecast system to service thousands of viewers from a standard business class internet connection. To accomplish this, Cablecast Reflect needs to be able to retrieve content from your Cablecast servers. This means before setting up your Cablecast Reflect account, you must provide Tightrope with public addresses, accessible from the internet, for every Pro, ProVOD, Live 330, and SX Live Server.

Setting Up Access

Cablecast Reflect needs to access port 80 via standard http. No other ports are needed. The most common way to setup access is through a port forward. A port forward works by mapping different ports on a single public IP address to different servers on the internal network. As mentioned in the warning above, when using port forwarding you must use external ports in the 1024 to 65535 range to be compatible with Cablecast Reflect. An example of a typical port forward setup is shown in the table below.

Another method of allowing Cablecast Reflect to access your servers is via network address translation (NAT). NAT works by mapping multiple external public IP address to internal IP address on your network. A typical NAT setup is shown in the table below.

You should consult with your network administrator to setup either port forwarding or NAT translation for your Cablecast system.

 

A Note On Security

As mentioned above, Cablecast Reflect only needs access to TCP port 80 on your Cablecast Servers. It is best practice to not allow other access ports to your system.
