It seems to me that you have it working again, or have I misunderstood you?
As far as it goes, I believe you have the ability to watch the Slingbox Pro while at home. However, remote viewing isn't working for you. If that's correct then I believe the problem remains in the Port Forwarding Rule. Most likely, the Slingbox has a new IP address but the Port Forwarding rule on your router hasn't been update to match the different address.
I would recommend in looking at the Slingbox's address from Slingplayer Desktop. From the command bar go to Help | About Slingbox <model> (Alt+E) | Information tab and within the "LAN" subsection you'll see the "IP address" and "Port" information. Make sure the port forwarding rule on matches this information.
Thanks for the reply.Unfortunately I cannot do as you suggest because I am away from home at the moment.While I was at home I noticed that there was no logo light and I just wondered if the lack of a light behind the logo was trying to tell me something.
I read somewhere that the logo light indicated that the Slingbox was working correctly.
