Kindly help me to configure a page rule that can be redirected to a single domain from all sub domains without creating a dns record for each sub domains.
If you want to do this for every possible subdomain, you would need an Enterprise plan. I am not sure what the purpose of this is, but fr the page rule to work, there needs to be an DNS record for the subdomain. Your wildcard DNS record will not have the option to proxy it unless you have an Enterprise plan.
