The following are the steps necessary to create a general purpose gateway to AMPRNet using an Ubuntu Linux Server.

Design

The basic design consists of three network connections:

  1. The first connection is to your ISP so you can reach the Internet.
  2. The second connection is used to connect your normal "non-ham" devices.
  3. The third connection is used to connect your "ham" devices so they can see and be seen by other AMPRNet devices.

The following diagram shows the layout of the connections. (Click on the image to enlarge).
