data. The TCP connection is
initiated from the privately
addressed workstation but the
video stream may be initiated
from the remote server. Because
a mapping does not already
exist for the UDP data stream,
the data can not be mapped to
a private address unless a static
PAT port has been defined or
the PAT default address is
configured.

Solution
First verify the possible
cause stated above is
actually the problem. Set
the Remote Site's PAT
default address to your
workstation's LAN address,
then try to run your video
application again. If it
works, check to see if your
video application allows you
to specify a static UDP port.
Microsoft NetShow allows
you to configure a static
UDP port in the Properties >
Advanced screen. After
setting a static port for the
video application, you must
add a corresponding static
port entry on the
OfficeConnect Gateway.
Set your Remote Site
default PAT address to
0.0.0.0 before you try the
static port.
If you cannot setup a static
port on the Video
application, check to see if
the Video application allows
you to specify TCP rather
than UDP. TCP streams are
typically initiated from the
private side.
If you still are unsuccessful,
the video application may
be embedding address and
port information within the
data portion of the frame. If
this is the case, consult your
application vendor for
possible workarounds.
