Opening Firewall or Proxy Ports for Ustream Broadcasting and Viewing

In order to broadcast or view streams, you will need to ensure that any firewall is configured to allow traffic on specific ports. A firewall can reside on your local machine, on your router, or as part of your corporate network.

Firewall settings needed for viewing streams

In order to watch Ustream streams you have to create the following stateful firewall rules, assuming you have a regular internet connection:

  • Outgoing UDP destination port 53 to your nameserver or any IP for domain name resolution (DNS)
  • Outgoing TCP destination port 80, 443 to any IP for web
  • Outgoing TCP destination port 1935 to any IP for streaming
  • Outgoing TCP destination port 843,6667 to the IP address ranges listed below for IRC chat
