Setting up sonicwall routers

So I have a Sonicwall router that I would like to get a certificate for. I could not find any documentation on setting up Letsencrypt on any system other then Linux/Apache. Any help would be greatly appreciated.

You’ll have to handle the request manually. Keep in mind that you will need some http service on the IP you’re using to validate the request. See List of Client Implementations for some options on how to make the request.
