The SlingMedia Slingbox is essentially a DVR control device that broadcasts your home cable signal through the Internet for remote viewing. Optimal performance of the remote viewing features across all software platforms requires a TCP connection. A Transmission Control Protocol (TCP) connection is one where two devices are connected during the entire duration of the information transfer to guarantee delivery, much like a phone call. Users who are unable to establish a TCP connection may use a UDP connection instead. User Datagram Protocol (UDP) relies on the hardware in between to correctly send the information to the correct place.

Skill level:
Moderately Easy


  1. 1

    Install your Slingbox Pro according to the onscreen instructions displayed during installation from the installation disk.

  2. 2

    Skip the instructions on setting up a port-forward for your Slingbox. The Slingbox will attempt to create a TCP port-forward and will revert to UDP mode if your network, router or firewall blocks TCP access.

  3. 3

    Connect to the SlingMedia Player from your laptop or desktop and use the software as normal.

Tips and warnings

  • Use TCP connections and port-forwarding for optimal performance.
  • UDP connections are slow and unreliable. Many Sling applications do not work with UDP connections.
