In episode 6 of our cyber security virtual lab building series, we continue with our OPNSense firewall configuration and configure the Multi-WAN failover and Load Balancing features, to create redundant paths to the internet. We will cover the VirtualBox network adapter configurations, setup gateway monitor and groups as well as modify some firewall and DNS rules to make this work.
By the end of this video, you will have a solid understanding of OPNSense Multi-WAN failover setups with some practical hands on experience completing this setup within VirtualBox. With slight adaptions these steps can be used in real-world production environments.
