The firewall must restrict traffic entering the VPN tunnels to the management network to only the authorized management packets based on destination address.
An XCCDF Rule
Description
<VulnDiscussion>Protect the management network with a filtering firewall configured to block unauthorized traffic. This requirement is similar to the out-of-band management (OOBM) model, when the production network is managed in-band. The management network could also be housed at a Network Operations Center (NOC) that is located locally or remotely at a single or multiple interconnected sites. NOC interconnectivity, as well as connectivity between the NOC and the managed networks’ premise routers, would be enabled using either provisioned circuits or VPN technologies such as IPsec tunnels or MPLS VPN services.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

Where IPsec technology is deployed to connect the managed network to the NOC, restrict the traffic entering the tunnels so that only the authorized management packets with authorized destination addresses are permitted.
