Well, I tried to find the manual for your router online, and the only ones I found do not give any instructions on how to assign a static IP local address to your Slingbox. As I read it, your manual implies that the router can only assign IPaddresses dynamically. I think you first need to assign a static IP address to your Slingbox, and then forward port 5001 to that assigned static IP address. But, as I read your online manual, if a device (like a computer) wants a static IP address, then the device itself must select its own static IP address. This is a straightforward thing to do on a computer, but I am not aware if, or how, the Slingbox can assign its own static IP address. So you might first want to check with your router manufacturer if they have a firmware update that allows the router to assign static IP addresses. Then, once you are able to assign a static IP address to your Slingbox, then forward port 5001 to that static IP address. Then reboot the router and the Slingbox, and hopefully it will allow you to view it outside the home network.
