With its <strong>Intel Quad-Core Celeron J3160 processor, AES-NI support, and four Intel Gigabit Ethernet ports<\/strong>, this compact device is <strong>built for speed, security, and reliability<\/strong>.<\/p>\n<p>But is it the <strong>right choice for pfSense or OPNsense<\/strong>? Let\u2019s explore its <strong>features, performance, and real-world applications<\/strong> to help you decide.<\/p>\n<hr \/>\n<h2><strong>Protectli Vault FW4B: Overview and Specifications<\/strong><\/h2>\n<p>The Protectli Vault FW4B is a <strong>barebone firewall micro appliance<\/strong> designed for <strong>pfSense, OPNsense, and other firewall distributions<\/strong>. Here\u2019s what you get:<\/p>\n<ul>\n<li><strong>Processor:<\/strong> Intel Celeron J3160 (Quad-Core, 1.6 GHz base, 2.24 GHz burst).<\/li>\n<li><strong>AES-NI Support:<\/strong> Yes (hardware-accelerated encryption for VPNs).<\/li>\n<li><strong>Ports:<\/strong> Four Intel Gigabit Ethernet ports (i211-AT).<\/li>\n<li><strong>RAM Support:<\/strong> Up to 8GB DDR3L (not included).<\/li>\n<li><strong>Storage:<\/strong> One mSATA slot and one 2.5-inch SATA bay (storage not included).<\/li>\n<li><strong>Power Consumption:<\/strong> Approximately 10W (energy-efficient).<\/li>\n<li><strong>Compatibility:<\/strong> Works with pfSense, OPNsense, Untangle, Linux, and Windows.<\/li>\n<li><strong>Design:<\/strong> Compact, fanless, and silent.<\/li>\n<\/ul>\n<hr \/>\n<h2><strong>Why Choose the Protectli Vault FW4B?<\/strong><\/h2>\n<h3><strong>1. Optimized for Firewall and VPN Performance<\/strong><\/h3>\n<p>The <strong>Intel Celeron J3160<\/strong> is a <strong>low-power but capable processor<\/strong> that handles firewall rules and VPN encryption efficiently. With <strong>AES-NI support<\/strong>, it ensures <strong>fast VPN speeds<\/strong> for OpenVPN, WireGuard, and IPsec.<\/p>\n<p>This makes the FW4B ideal for:<\/p>\n<ul>\n<li>Home labs.<\/li>\n<li>Small business networks.<\/li>\n<li>Remote workers needing a <strong>secure VPN gateway<\/strong>.<\/li>\n<\/ul>\n<h3><strong>2. Four Intel Gigabit Ethernet Ports<\/strong><\/h3>\n<p>Unlike many budget alternatives, the FW4B includes <strong>four Intel Gigabit Ethernet ports<\/strong>, which are <strong>more reliable<\/strong> than Realtek NICs. These ports are <strong>fully compatible<\/strong> with pfSense, OPNsense, and Untangle, making it perfect for <strong>multi-WAN setups<\/strong> or load balancing.<\/p>\n<h3><strong>3. AES-NI Support for Faster Encryption<\/strong><\/h3>\n<p>If you\u2019re running a <strong>VPN server<\/strong>, AES-NI hardware acceleration is a <strong>must-have<\/strong>. It ensures <strong>faster encryption and decryption<\/strong>, reducing CPU load and improving performance.<\/p>\n<p>Without AES-NI, VPN speeds can drop significantly\u2014sometimes by <strong>50% or more<\/strong>.<\/p>\n<h3><strong>4. Compact, Fanless, and Energy-Efficient<\/strong><\/h3>\n<p>The FW4B is <strong>silent and energy-efficient<\/strong>, consuming only about 10W of power. Its <strong>compact design<\/strong> makes it easy to place in a home office or server rack.<\/p>\n<h3><strong>5. Barebone Design for Customization<\/strong><\/h3>\n<p>The FW4B is sold as a <strong>barebone unit<\/strong>, meaning you\u2019ll need to add:<\/p>\n<ul>\n<li><strong>RAM<\/strong> (4GB to 8GB DDR3L recommended).<\/li>\n<li><strong>Storage<\/strong> (mSATA or 2.5-inch SATA SSD).<\/li>\n<li><strong>Optional Wi-Fi<\/strong> (via USB adapter if needed).<\/li>\n<\/ul>\n<p>This allows you to <strong>customize the system<\/strong> based on your budget and requirements.<\/p>\n<hr \/>\n<h2><strong>Setting Up the Protectli Vault FW4B<\/strong><\/h2>\n<h3><strong>Step 1: Add RAM and Storage<\/strong><\/h3>\n<ul>\n<li><strong>Recommended RAM:<\/strong> 4GB to 8GB DDR3L (8GB for heavy VPN use).<\/li>\n<li><strong>Recommended Storage:<\/strong> 120GB to 250GB SSD.<\/li>\n<\/ul>\n<p>Example components:<\/p>\n<ul>\n<li><strong>RAM:<\/strong> Crucial 8GB DDR3L<\/li>\n<li><strong>SSD:<\/strong> Samsung 870 EVO 250GB<\/li>\n<\/ul>\n<h3><strong>Step 2: Install Your Firewall OS<\/strong><\/h3>\n<p>The FW4B works seamlessly with:<\/p>\n<ul>\n<li><strong><a href=\"https:\/\/www.pfsense.org\/\" target=\"_blank\" rel=\"nofollow noopener noreferrer external\">pfSense<\/a><\/strong><\/li>\n<li><strong><a href=\"https:\/\/opnsense.org\/\" target=\"_blank\" rel=\"nofollow noopener noreferrer external\">OPNsense<\/a><\/strong><\/li>\n<\/ul>\n<p>We recommend <strong>OPNsense<\/strong> for its <strong>modern interface and free features<\/strong>.<\/p>\n<h3><strong>Step 3: Configure Network and Security Rules<\/strong><\/h3>\n<ul>\n<li>Set up <strong>WAN and LAN ports<\/strong> in your firewall OS.<\/li>\n<li>Enable <strong>AES-NI acceleration<\/strong> for VPNs.<\/li>\n<li>Configure <strong>firewall rules, VPN, and intrusion detection<\/strong> as needed.<\/li>\n<\/ul>\n<hr \/>\n<h2><strong>Protectli Vault FW4B: Pricing and Availability<\/strong><\/h2>\n<p>The <strong>Protectli Vault FW4B (barebone)<\/strong> is available
