NET0987 - Managed network has access to OOBM gateway router - 'ip receive acl IP_RECEIVE_ACL'

Information

Traffic from the managed network is able to access the OOBM gateway router.

If the gateway router is not a dedicated device for the OOBM network, several safeguards must be implemented for containment of management and production traffic boundaries. It is imperative that hosts from the managed network are not able to access the OOBM gateway router.

NOTE: Change 'IP_RECEIVE_ACL' to the access control list number for IP receive filtering.

Solution

Ensure that traffic from the managed network is not able to access the OOBM gateway router using either receive path or interface ingress ACLs.
