Description:

The Darwin Streaming Proxy is an application specific proxy which
would normally be run in a border zone or perimeter network. It
is used to give client machines within a protected network access
to streaming servers outside that network, in the case when the
firewall blocks RTSP connections or RTP/UDP data flow. The
firewall perimeter network is usually configured to allow:

* RTSP connections from within the network, as long as the
destination is the proxy

* RTSP connections to outside the network, as long as the source
is the proxy

* RTP datagrams to and from the proxy to the inner network

* RTP datagrams to and from the proxy to the outside
