Some routers may have other security settings that need to be modified for your Pull stream to be visible
from the outside. For example, the Linksys® router shown above has a setting in the Security page named
Block Anonymous Internet Requests. While this may be a great idea normally, it’s not going to help much
when outside computers request that your system permit them to Pull the video stream, is it?
There are countless makes and models of routers – for information on various models, and a great deal of
help on port forwarding generally, we can recommend the following site:

Firewalls:
You may also run into software firewalls. Generally, these can be configured in similar to permit exceptions
to the firewall policy, permitting specific ports or applications to be opened to the world. Information on
exceptions in the Windows

Firewall can be found in its Help system.

NUMBER
Again, the numbers assigned behind your router only work locally. In a Pull scenario, you need to supply the
true external IP number (and port) for your TriCaster to viewers outside the LAN (Local Area Network).
You can find this number in several ways. For example, your router will display it as its “IP Address” in its
Status page. Or, you may want to use one of several handy websites that will quickly supply your current IP
number (one such is http://www.whatismyip.com). Simply go to the website in your browser and read the
IP number from the screen. Append a colon and the port number you are using to this number and you’ve
got everything you need for your viewers to connect.

Are you sure your upload bandwidth is adequate to the bitrate you’ve set for your stream? Why not test and
make sure. Again, a number of websites provide free speed testing. These will give you a basic idea of what
your local bandwidth really is. One site which provides a list of online speed test resources is:

IS IT REALLY A TRICASTER ISSUE?
With regard to streaming issues, don’t overlook the fact that TriCaster is just one of the pieces of the puzzle.
There are many others that are just as important.
Here are some useful things to try:

Check the file:
Archive the streaming output file locally, and then examine it to see if it has any problems. This file
corresponds exactly to what TriCaster is sending the downstream server. In cases of sync problems,
low frame-rate problems, audio popping problems, etc., if it's a TriCaster issue, the problem will be
