Build Secure and Scalable Networks Using DHCP & VLANs in OPNsense
What you'll learn
✓ Explain how DHCP works at a protocol level, including the DORA process, broadcast and unicast behavior, lease allocation, and client-server interactions.
✓ Configure and manage DHCP services on OPNsense, using both ISC DHCP and Kea DHCP, and select the appropriate service based on real-world use cases.
✓ Design and implement VLAN-based network segmentation on OPNsense, including VLAN creation, interface assignment, and proper integration with DHCP services.
✓ Bind DHCP services to VLAN interfaces and apply correct firewall rules, ensuring secure communication, proper routing, & controlled access between segments
✓ Troubleshoot common DHCP and VLAN issues, such as clients not receiving IP addresses, connectivity failures, ARP-related problems & routing misconfigurations
✓ Apply best practices for secure and scalable network design, suitable for enterprise environments, ISP networks, and lab or training deployments.
Requirements
● Basic networking knowledge is recommended, such as understanding IP addressing, subnetting, and fundamental TCP/IP concepts.
● Familiarity with network devices (routers, switches, or firewalls) is helpful but not mandatory.
● No prior OPNsense experience is required; the course starts from the basics and builds up step by step.
Description
This course provides a comprehensive and practical guide to implementing DHCP and VLANs using OPNsense.
It is designed for network engineers, system administrators, and IT professionals who want to build secure, scalable, and well-segmented networks using OPNsense in real-world environments.
You will learn how DHCP works from the ground up, including address allocation, lease management, and client behavior, before applying these concepts directly on OPNsense. The course covers both ISC DHCP and Kea DHCP, explaining their differences, use cases, and configuration approaches within OPNsense.
VLAN concepts are explained clearly and then implemented step-by-step, showing how to design segmented networks, bind DHCP services to VLAN interfaces, and apply appropriate firewall rules. Special attention is given to common pitfalls such as connectivity issues, ARP behavior, routing problems, and misconfigured firewall policies.
The course is hands-on and lab-driven, focusing on practical scenarios you may encounter in enterprise networks, ISPs, labs, and training environments. By the end of the course, you will be able to confidently deploy, troubleshoot, and maintain DHCP and VLAN configurations on OPNsense.
Additionally, the course emphasizes best practices, performance considerations, and security implications, helping you understand not only how to configure services, but also why specific design choices matter in production networks.
Who this course is for
■ IT professionals responsible for deploying or managing firewalls and network infrastructure
■ Network engineers who want to design segmented and secure networks using VLANs
