Evaluate hardware for home, small business, and enterprise firewall deployments, highlighting the zima board and protective vault v1610 for multiple LAN and WAN interfaces with open sense support.
Discover the Protectli Vault V1610 with six 2.5 Gbps ports, enabling WAN failover, link aggregation, and network isolation. Run OpenSense on Proxmox with PCI passthrough for firewalling and NAS-backed virtualization.
Download and prepare installation media for opnsense firewall by choosing a dvd iso, virtual machine, or usb boot image, then extract and name the iso for bare-metal or virtual installations.
Download the VGA img for the USB installer, extract it with WinRAR, and flash to a 16 gb USB drive using Balena etcher. Validate disk and remove USB when complete.
Step-by-Step Installation Guide on Any Hardware
Install Proxmox VE on Protectli hardware via ISO or USB, choose Proxmox VE 8.3.0, flash with Balena Etcher, and configure 2 TB storage to host Open Sense and network solutions.
Install OPNsense on Proxmox with step-by-step VM setup, pass through three NICs for WAN, LAN, and Wi‑Fi, and configure interfaces and management IPs.
Log in to the OPNsense web user interface and view the dashboard with firewall and traffic stats. Configure interfaces, gateways, VPNs, firewall rules, backups, firmware from the web user interface.
Master the OPNsense system configuration basics, including administration settings, port changes, authentication options, SSL certificates, logging, and scheduling automatic firmware updates and reboots.
Configure wan and lan through the cli by assigning vnet zero and vnet one, set ipv4 addresses and dhcp, then access the OPNsense web gui for final setup.
Learn to add and assign a new interface, create a second network, and configure IPv4 static addresses across two networks.
Create a network bridge in OPNsense and connect it to the LAN with a new management IP range. Assign 192.168.24.1/24, save changes, and verify connectivity by pinging the bridged network.
Explore how the GIF generic interface tunnel connects IPv4 and IPv6 networks using a simple tunneling protocol. Learn to implement cross-version links with the GIF tunnel.
Discover how a link aggregation group combines multiple network interfaces into one, boosting bandwidth, enabling redundancy and load balancing with lacp across switches in opnsense.
Explore loopback interfaces as virtual, non-physical tools for testing routing in OPNsense. Create a loopback interface, such as Sync Bricks, for isolated testing not connected to external or physical networks.
Explains point-to-point connections for linking OPNsense directly to an internet service provider, using wan or bridging the provider's router to enable a direct high-speed, low-latency connection.
Create and manage vlans on the lan, assign tags 10 and 20 for servers and guest wifi, configure static ipv4 192.168.1.1/24, adjust dhcp ranges, and note vxlan for very large networks.
Explore OPNsense interface diagnostic tools, including arp and ndp tables and ipv4/ipv6 neighbor information. Use netstat, packet capture, ping, port checks, and trace routes to diagnose connectivity and active connections.
Learn how to configure and map OpenSense interfaces with Proxmox and VMware, including WAN via DHCP, PCI passthrough, VNet zero and one, and VM IP provisioning from OpenSense.
Learn how the dynamic host configuration protocol automates IP address delivery, assigns parameters via a DHCP server, uses mac addresses to track devices, and leases address assignments in pfSense networks.
Configure the KEA DHCP server in OPNsense, define subnets for wireless LAN and home lab, switch from ISC DHCP, create reservations, enable interfaces, and automate firewall rules for DHCP traffic.
Celebrate your commitment to mastering network security with this course, seek feedback to improve, and stay consistent as you progress through the OPNsense firewall guide.
Explore the basics of OPNsense firewall rules, learn how to block or allow traffic between networks and the internet, and apply interface, floating, and VLAN rules.
Create and manage aliases in OPNsense firewall to group hosts, networks, ports, and URLs; apply firewall rules to these aliases for devices, web servers, and IP ranges.
Learn to create and apply firewall rules using aliases on the wireless LAN, blocking internet access for alias groups and ensuring IP changes require no rule edits.
Define night time and daytime schedules in OPNsense to block or allow traffic, including weekend rules and server update windows (Friday 12 am–2 am).
Set up a firewall rule that uses a night time or full day schedule to block a device alias, ensuring the schedule is active and time is correct.
