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:
- The first connection is to your ISP so you can reach the Internet.
- The second connection is used to connect your normal "non-ham" devices.
- 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.
