OPNsense: Open-source security platform
OPNsense is the core router platform I default to for all my network infrastructure (work devops env, homelab, vpn to family members etc). Its feature packed and ROCK solid. I almost always run it in a virtual machine so i can live migrate it between hosts and have no downtime. The cluster &#x2F; high availability works great and ensures no loss of connectivity during upgrades. OPNsense is a true hidden gem in the open source world.
