Webinar Technical Requirements

We’re often asked what the specific requirements are for a company or individual to present on or attend a live WorkCast event. Here’s the low-down on all things technical.

Not using a proxy server/VPN is recommended


  • VPNs are typically not designed or configured to support real-time media.

  • Connectivity to WorkCast might not be efficient due to hair-pinning traffic through a VPN device.

When it comes to WorkCast traffic over proxies, we recommend bypassing proxies. Proxies don't make WorkCast Studio more secure because the traffic is already encrypted.

And having a proxy can cause issues. Performance-related problems can be introduced to the environment through latency and packet loss. Issues such as these will result in a negative experience in such WorkCast Studio scenarios as audio and video, where real-time streams are essential.

If you need to use a proxy server
Some organisations have no option to bypass a proxy for WorkCast traffic. If that's the case for you, the problems mentioned above need to be kept in mind.
We also strongly recommends:
  • Using direct UDP based routing
  • Allowing UDP traffic

For attendees and presenters there are no WorkCast downloads or plugins required.

Onsite Live Video Stream requirement 

If you have chosen the Live Stream presentation type there will be an onsite AV team and they will be pushing their content via a vision mixer to the WorkCast platform via onsite streaming technology. The venue will need to review the below information prior to the on day live stream. 

Stream Format

Firewall TCP Ports (inbound and outbound)


RTMP (real-time messaging protocol)

All of the following:


NOTE: RTMP traffic must also be allowed through the firewall.
