Hi @JAMES2219,

Thank you for visiting SonicWall Community.

Please try adding a rule WiFi to LAN as given below.

Source: X0:V20 Subnet, Destination: X0 Subnet, Service: Any, Action: Deny.

This rule should only affect denying the traffics from V20 subnet to X0 subnet. All other traffics are allowed.

Hope this helps.

@James2219 - Yes, you are right. The deny rule should have the top priority. Please have priority 1 for the deny rule.

Hope this helps.
