D-Link DFL-870M Gigabit Enterprise Firewall

A Defined Security Boundary for the Business Network The DFL-870M brings firewall policy, application inspection and VPN capabilities into a 1U rack appliance. Ten Gigabit copper ports and two Gigabit copper/SFP combo ports provide 12 logical data interfaces for a deliberately segmented network. Each combo pair is one usable interface, rather than two independent ports. The hardware includes 2 GB memory, 4 GB flash and one hardware bypass pair. Security services, routing and monitoring functions are configured around the network policy. Antivirus, IPS, application-control and web-filter signature subscriptions are separate entitlements; the hardware offer does not establish an included paid update term. Highlights Hardware 10 × Gigabit copper interfaces. 2 × Gigabit copper/SFP combo interfaces. 12 logical data ports and 1 hardware bypass pair. Security Functions Stateful firewall, access policies and VPN. Traffic inspection, application and bandwidth controls. Signature services require the appropriate entitlement. Deployment 19-inch, 1U rack format. 2 GB memory and 4 GB flash. Web, CLI, logs and SNMP administration. 5-year warranty. Key Features Separate the Network With Clear Interfaces Ten copper interfaces and two copper/SFP combo interfaces provide a flexible connection layout for the network design. The combo sockets share their logical interfaces, so copper and optical sides are not counted as separate simultaneous ports. Select compatible SFPs and define the WAN, LAN and security zones during commissioning. Apply the Security Policy at the Gateway Stateful inspection, access policies, NAT and attack controls support a defined boundary between network segments and upstream connections. The system supports multiple deployment modes, including routing and transparent operation. The correct mode and rule set follow the topology and security requirements, rather than a universal default configuration. Inspect Traffic With the Right Entitlement The platform supports antivirus, intrusion prevention, application control and web filtering functions. Signature databases and update services depend on the appropriate licensed entitlement. Select and verify the required service term before relying on updated inspection data; a hardware purchase alone does not promise every subscription feature is active. Connect Sites and Control Traffic VPN, routing, link controls and traffic-management functions support business connectivity. The manufacturer lists 1 Gbps VPN throughput under its test conditions. Actual performance depends on encryption, packet sizes, inspection services and concurrent traffic, so capacity planning should use the workload expected in the installation. Design the Failure Response Deliberately One hardware bypass pair and high-availability functions provide options for a planned failure response. Bypass behaviour can affect which security functions remain in the traffic path. Choose the required fail-open or fail-closed policy, test the wiring and document the operational response before using the appliance on a critical connection. Keep Administration Visible and Controlled Web management, CLI, SNMP, system logs and diagnostic tools help administrators observe traffic and investigate faults. Restrict management interfaces to trusted networks, use appropriate authentication and retain recovery configurations. Monitoring, software maintenance and a tested response process remain part of the security deployment. Summary The DFL-870M provides a rack-mount security gateway with 12 logical Gigabit interfaces, configurable inspection and network controls. Match the hardware, topology and required signature subscriptions to the security policy, then test the complete configuration before deployment. Frequently Asked Questions How Many Data Ports Does the DFL-870M Have?ExpandCollapse It has 10 Gigabit copper interfaces and 2 Gigabit copper/SFP combo interfaces, for 12 logical data ports. Each combo pair uses either its copper or optical connection, not both as independent ports. Are the Antivirus and IPS Update Terms Included?ExpandCollapse No paid update term is established by this hardware listing. Antivirus, IPS, application-control and web-filter services require the appropriate separate entitlement and activation. Are Optical Transceivers Included?ExpandCollapse Select supported optical SFPs separately for the combo interfaces. Match the fibre type, distance, wavelength and remote endpoint. Is This the Same Hardware as the Base DFL-870?ExpandCollapse No. The DFL-870M has its own hardware configuration, including 10 copper ports, 2 combo interfaces, 2 GB memory and 4 GB flash. Use the exact M-model specifications when planning the installation. What Do the Performance Figures Mean?ExpandCollapse Manufacturer maximums are measured in specified conditions. Enabled inspection services, encryption, packet size, connection rate and traffic mix affect actual performance. They are not simultaneous guaranteed throughput figures. Does Bypass Guarantee Continuous Protected Traffic?ExpandCollapse No. Bypass and high-availability functions must be designed and tested for the installation. A bypass path can change which inspection functions remain active, so define the required failure policy before deployment. Magbasa pa
