The issue that you are having might be caused by the Internet Viewing settings on the Slingbox, since you are not able to connect to the Slingbox using the iPad or your Android phone.
Use the following links in order to get a guide on how to enable this setting manually, in order for you to connect remotely.
I wanted to change the default port that the slingbox uses. I have followed the network setup and put in my ip address, the gateway and the perferred port I'd like to use. It's open on my router. However, my slingbox solo is still showing port 5001 on the home page of info. What am I doing wrong? Thanks.
