Configure your Computer to Have a Static IP Address

Port forwarding the Cisco 870 Series to your computer can be more reliable if you first configure a static IP address on your computer. We have instructions to setup a static IP address for Windows 7, Windows 8, and a variety of other devices on our Static IP Address Settings page.

Please note that while setting up a static IP address on your computer is optional, it is still a very good idea to go ahead and do it. In the long run it will make your port forward much more reliable.
