Hello,
The slowness comes from the additional overhead of TCP compared to UDP. I
unfortunately do not have more specifics. My information concerning Real
Audio came from the folks who set up our enterprise firewall. They found
the solution to the Real Audio issue. With hope, someone on the list might
have more intimate first hand experience with Real Audio through firewalls.
There is also some more information at
<http://service.real.com/firewall/index.html>
Hope this helps,
Ken
