Planning for Network Access Protection

In addition to standard ConfigMgr traffic, NAP generates the traffic described in Table 5.2. If you use firewalls that block this traffic, you must reconfigure them for NAP to work with ConfigMgr. You will also need to identify ports used by the client to the system health validator point. ConfigMgr does not use the ports listed in the table directly; they are established by NAP and dependent on the enforcement client being used.
