I think you should provide more information about the rule you created.
Deny everything, Permit only private address range, specifically the subnet the device is on.
A firewall usually reads the rules from top to bottom and applies the first match. So when your first rule is deny everything , it will deny literally anything before the second rule will be applied.
Your deny rule should always be at the end.
