This chapter presents the complete firewall configuration hierarchy available on J-series Services Routers and SRX-series services gateways running JUNOS software.
Use the statements in the firewall configuration hierarchy to configure stateless firewall filters—also known as access control lists (ACLs)—on the device. Stateless firewall filters allow you to filter packets based on their components and to perform an action on packets that match the filter. For configuration instructions, see the JUNOS Software Interfaces and Routing Configuration Guide.
For information about these firewall statements that are shared across Juniper Networks devices—see the JUNOS Policy Framework Configuration Guide.
