Does anyone know how to use WSUS Server in NAC Appliance. I can able to authenticate in the network with the clean access agent. But everytime I used the WSUS requirement it pass through from normal login role to temporarily role for remediation. Im using a WSUS server. So it will lookup to WSUS requirement but the problem I cannot able to remediate using it, I got error message. Do I need to allow some ports in the network to make it work? What ports do I have to open? Please see attachment. Thanks.
When you use WSUS with NAC, all the NAC agent does is to tell the Windows Update agent to go update itself. Now it depends on the WSUS setting on the client where it will go to check for updates. If you have it configured for MS servers, it will go talk to them. If you have your clients configured for internal WSUS server, it will check in with them.
Here are details on how to set the registry keys for both scenarios (AD and non-AD)
