v2.2.1
Add A Preflight Check function. When running the auto-config via SSH, there is a button to:
- Router responds to SSH.
- Username and Password are correct.
- Router is firmware >1.8 (I had an issue with the Configurator on an ErX running 1.7 that was resolved by upgrading to the latest 1.x firmware)
- If 'keys are store on router' is selected, keys exist.
- Grep existing firewall rules for the VPN port; 'green' if it doesn't exist or is already forwarded to router, 'red' if it's pointing somewhere else (recommend user change port)
