(So, for example, you might type: ping –c 4 192.168.1.101)
The response will be similar to the Windows® example described above. Again, a
ping failure indicates a problem with the network connection.
PULL CONNECTION ISSUES
Note that - if you are Pull streaming from ‘behind’ a router – the IP number shown in
the TriCaster’s Location field will only be valid for other systems behind the router.
You will need to derive the true external IP address to pass to your viewers (or service
provider.)
Again, in this environment you may wish to consider Push streaming with the aid of a
Content Delivery Network (a commercial service), as this is generally free of firewall and
router woes that often require a friendly system administrator to resolve otherwise.
You will also need to enable “port forwarding” on the router, as discussed next.
Port Forwarding
If you are streaming from behind a router, to preserve a reasonable level of security
while allowing outside computers to connect to your system you will need to ‘port
forward’ your router.
Port forwarding permits a sort of ‘blind hand-off’ between external clients (your
viewers) and a local transaction port which you manually specify. (The router will
pass requests to view the stream through to the TriCaster, without exposing the
internal IP routing.)
To enable port forwarding, you need three pieces of information:
The login information for the router. Your router’s manual will have this
information, which typically involves entering a specific IP number into your
web browsers URL field, and perhaps also a password you have set
previously.
The specific IP local number that the router has assigned to your TriCaster.
You can read this right from TriCaster’s Location display. It will comprise the
entire string of punctuated numbers before the colon (the colon separates the
port number you chose for your stream).
