Internet Connection and Open Ports for Feedbox

Internet Connection and Open Ports for Feedbox

An adequate internet connection is the key to a successful live webcast.  The encoder requires direct access to the internet, but access to any internal hosts on your network is not required. If the encoder is to reside behind a firewall, internet access outside of the client firewall will be requested by iSiLIVE.  Depending on the quality of the stream, the allotment of bandwidth may change.  In our experience, usually a dedicated DSL connection will suffice for a single stream.  The internet access point should be within close proximity to the webcast/video switching work station.


iSiLive requires a few network configuration items. The encoder will need to send and receive data on the ports below:


NOTE: These ports are all outbound, NO inbound ports are required to be opened. If you're using SonicWall (or other similar application-specific device that does packet and state inspection), please ensure RTMP/RTMPS and SSH protocols are not blocked for the feedbox. This will prevent the control and broadcast systems from working properly regardless of port availability.


DNS (domain name system):
  1. Unless specified by your organization, our encoders will ship using trusted public DNS servers by default: e,g, Google (8.8.8.8, 8.8.4.4), Cloudflare (1.1.1.1), UDP/TCP port 53
NTP (network time protocol):
  1. Time synchronization is typically optional, but using NTP we can ensure timestamps in logs agree for troubleshooting purposes; some future features (e.g. time overlay on video) will require time synchronization.
  2. Unless specified by your organization, our encoders will ship using trusted public NTP servers by default: e,g, NTP.org (0.pool.ntp.org, 1.pool.ntp.org), UDP port 123
