ubiquiti USG bootstrapping

When installing a new ubiquiti USG router device, or when installing a new firmware, the following manual steps will be necessary:

Dyanmic DNS

Cloudflare is not supported out-of-the-box, therefore the following blog post and associated gist reveal what is necessary:

curl https://gist.githubusercontent.com/troyfontaine/7e6f93e32621177fc9a94e823adc52b5/raw/fix_ddns.sh | sudo bash

The necessarey configuration is already persisted in the config.gateway.json file on the controller.

WireGuard

https://github.com/WireGuard/wireguard-vyatta-ubnt has the necessary instructions.

The necessarey configuration is already persisted in the config.gateway.json file on the controller.
