Set Static IP for Device

Setting a Static IP on your device only refers to your internal, home network. This has no effect on your Internet service.
It is critically important you setup a Static IP for your device, before you setup port forwarding. Without doing so, you could easily lose all your port forwarding setup, and expose other devices that may not be as well-secured to malicious attack on the Internet.
  1. Locate and identify where in your router's interface you can setup an Address Reservation. In this example, it was under Advanced > Setup > LAN Setup, then scroll down to Address Reservation at the bottom.

The following steps will provide general guidance on setting up port forwarding.

This is usually not necessary with modern devices, services, and programs, and carries with it a number of rather serious security concerns.

Also, these instructions will be general, and may be difficult to follow without knowing your specific router very well. Each router is slightly different in how they setup port forwarding, as well as exactly which menu, option, and area each step is located.

If you are having problems with a specific device getting online, it's recommended to review the article specific to troubleshooting that device here, or contact the device manufacturer before trying to use port forwarding to solve the problem.
Given the huge variation in routers, these instructions will not be exact, nor will you be able to follow them exactly to enable port forwarding. It is recommend you contact your router manufacturer if you need specific direction or are unable to locate the suggested areas to look.
