I noticed that you are not able to connect to the Slingbox locally. Since it is detected on the router, the issue might be caused by a security setting on your computer.
I recommend you to follow the instructions on this link:
If the issue persists, you might want to try to configure the Slingbox with another computer. Let us know if it worked.
Thanks for replying Cristina.
I actually used Windows Slingplayer v2 and I was then able to see my Slingbox on my network and set it up. Using the Internet version of Slingplayer seemed to be my problem. Once my Slingbox was setup using the old Windows Slingplayer desktop software everything worked fine.
I also had to install the old software to get my Slingbox working on my parents network, because when I moved it to the parents house I had the same problem with not being able to see my Slingbox using the Internet version of Slingplayer.
All is now well with the world and the family can now watch the VOICE in the Philippines
