How to use Skynode's Internet connection on the AI Node

The following section describes how to set up AI Node and Skynode, such that AI Node uses Skynode as an internet router.
Before starting, make sure you have connected AI Node to Skynode.
Only ETH0 of AI Node can be readily used for internet sharing.
Both Skynode and AI Node come with ready-to-use infrastructure for sharing Skynode's internet connection. This is, however, disabled by default.
To configure the internet sharing, both devices have to be configured by modifying environment variables. For a single temporary test setup the environment variables can be added to /data/override.env. For a fleet-wide configuration use the Auterion Developer Tools to permanently modify AuterionOS. Refer to the following page for more details on both methods:
SSH into Skynode and set the environment variables in /data/override.env as shown below.
Power-cycle Skynode for the changes to take effect.
SSH into AI Node and set the environment variables in /data/override.env as shown below.
Power cycle AI Node for changes to take effect.
You can now try to access the internet from AI Node, assuming Skynode is already connected to internet:
Skynode and AI Node can address each other via static IPs when configured as described above. In theory, you can use any IP addresses for the configuration as long as the following is true:
Network prefix is 16 or 24
AI Node is connected to Skynode via ETH0
IP range is not 10.41.1.0/24 or 10.41.2.0/24, as these are reserved for the respective USB debug interfaces of Skynode and AI Node.
AI Node only accepts AuterionOS updates from the limited number of subnets, which are:
10.41.2.0/24 (reserved for USB Debug)
10.41.3.0/24 (used in example above)
172.20.0.0/16 (default range of ETH0 on AI Node)
10.223.0.0/16
It is thus strongly recommended to configure the link between AI Node and Skynode based on the IP ranges (3) and (4) in the list above. Otherwise local AuterionOS updates from Skynode and / or AI Node will not be possible. AuterionOS updates executed via Auterion Suite are unaffected and work as long as there is a internet connection.
