How do I add a wildcard subdomain, i.e. *.sso.mydomain.net

Hi, I would like to use the buzzfeed sso proxy to add authentication to all my internal home lab sites.
See: https://github.com/buzzfeed/sso

To do this I need to add a *.sso.mydomain.net record that points to my sso proxy IP.
My current DNS provider, eNom, does not support a 4th level subdomain, as far as I can tell at least.

How would I do this with a free cloudflare account, I don’t know how to add the sso subdomain?

You can add that wildcard, but you won’t be able to set it to :orange:. The entry should just be *.sso and then the IP address or CNAME.

I assume that if I already have certs it will work, minus as @sdayman stated no protection?

Unless you’re on an Enterprise plan, you can’t proxy wildcard subdomains.
