|Minimal Firewall settings needed for
UPLOADING and VIEWING webcasts
To broadcast/upload and watch streams you need the following stateful firewall rules, assuming you have a regular internet connection (if you are behind a corporate firewall ensure your IT department configured the firewall to these settings):
•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 (WEB)
•Outgoing TCP destination port 1935 to any IP = RTMP (to deliver the stream)
Some firewalls reject traffic that
doesn't use the HTTP protocol. This behavior can prevent
communication over RTMP even if port 1935 is open. Consult the
documentation for the firewall to determine how to configure it
to allow RTMP traffic. To use RTMP and RTMFP, firewalls
between the server and clients must allow inbound and outbound
traffic on port 1935.

common encoding parameters like those used for this page's Flash stream...note the "Total bandwidth required to stream" info - that's the upload speed required on-site to the server, whereas the "Bit Rate" is the bandwidth the Viewer needs to download the live stream.
The flash player at the top of this page is embedded in an iframe which makes a call to a Flash server for the stream. Note that there are cross-browser differences when embedding iframes. (this page is usually optimized for Google Chrome)
