The Netgate® 4100 with pfSense® Plus software is one of the most versatile security gateways in its class. It combines the power of a Dual-Core Intel® Atom® C3558 Core CPU with integrated QuickAssist & AES-NI, and 4 GB of memory for a snappy user experience, delivering over 8.15 Gbps of L3 routing across six independent – (2) 1 GbE and (4) 2.5 GbE – flexible WAN/LAN ports. The Netgate 4100 is ideal for pro-home, small/medium businesses, or edge deployments that require flexible port configurations to support 1 to 2.5 Gbps WAN capabilities across (2) RJ45 copper / SFP fiber Combo WAN ports and (4) discrete, unswitched 2.5 Gbps RJ-45 ethernet LAN ports – all in a silent desktop form factor. With a fanless design, the product is suitable for desktop, wall mount, or rack mount deployments. Factory-provisioned with pfSense® Plus software makes it ideal for a broad range of edge firewall, VPN, and router use cases.

CPU: Intel® Atom® C3338R with QAT, 2-core @ 1.8 GHz. Delivers 8.15 Gbps routing for common iPerf3 traffic and over 4.09 Gbps of firewall throughput. Network Ports: 6 Independent 1G and 2.5G Flexible WAN/LAN Configurations. Use a combination of 6 ports for maximum flexibility - with 1 and 2.5 Gbps WAN capabilities across RJ45 and SFP ports, as well as 4 discrete, unswitched 2.5 Gbps LAN ports Storage: 16 GB eMMC (or optional 128 GB NVMe M.2 SSD with Netgate 4100 Max) Memory: 4 GB DDR4 RAM, DDR4 memory allows more stable, higher transfer rates for memory-intensive applications (e.g. IDS/IPS). Cooling: The passive cooling system and low power draw of the Netgate 4100 provides efficient thermal management and silent operation expected from smaller devices despite its significantly higher performance.
