IPv4 Policy Deny internet access not working

Hello,

I am trying to setup a Policy to block specific computers on my network from being able to access the internet. I created a new policy with Incoming interface set to LAN (internal), Outgoing Interface to WAN, the Source to m2mwork9 which is the name of the pc. Set the Destination to ALL, the Schedule to Always, the service to ALL, and Action to DENY. I moved the policy to the top of my LAN-WAN policy group but I am still able to access the internet with that computer. I have read the cookbook and watched a bunch of videos but no luck figuring out what I am missing.
