Endpoint Protection

My company is using SEP's firewall as it's main source to block users from accessing our servers.

I'm using the attached firewall rules, but they're still not just allowing the Host's I specified to connect. I'm able to plug in a laptop not in the host list and access our servers.

I would like some assistance to know if what we're trying to do is possible, or if we need to find a different solution.

Thanks

In addition are you getting any data showing up in the Traffic log?
 

I do not know where to find the Traffic Log, but the policy is set up to record it.

Open the client and go to View Logs >> Network Threat Protection >> Traffic log

I'm getting some from one server that shows that the policy is working, but from another one in the same group, it's allowing the laptop to connect to the server.

Are my rules set up correctly? Or do i need to change something?

and just as a quick confirmation, the client that is allowed, did it get the updated policy/is connected to the SEPM?

Yes, all policies are updated and the servers are connected to SEPM. They are in the same policy group, yet some servers allow connection to them while others do not.
