No Open Port On Your Router
A port must be open on your router to watch your Slingbox remotely. By opening a port on your router, your router allows access to your Slingbox when
you attempt to watch your Slingbox from a remote computer. If the port is not open, your router does not allow outside access, as shown below.
Solution: If the Setup Wizard did not automatically open a port on your router, go to www.slingmedia.com/portforward.html to try the Setup Wizard
port-forwarding tool. If this does not provide sufficient help, refer to your router documentation or the support Web site for your router manufacturer.
Multiple Routers In Your Home
With the growth of wireless networks and combination network devices, some home networks have become overly complex with the use of multiple routers
when just one can do the trick. If you have multiple routers in your home, the ports must be open along the path. It is possible you have multiple routers in
the home, even if you don't think you own more than one. How is this possible?
• Some DSL/Cable modems have built-in router functionality. For example, DSL modems made by 2Wire, and select models by Westell and
SpeedStream have built-in router functionality.
• If you have a Voice-over-IP (VoIP) server in your home, it may also act as a router. In this case, the VoIP server is actually your primary router.
In a multiple router home where Slingbox is connected to a secondary router, as shown below, you need to open a port on both routers to watch your
Slingbox remotely. It is strongly recommended that you connect your Slingbox to the primary router in your home, as shown.
