VNET virtual network stacks are a powerful network stack isolation technology that gives FreeBSD jails super powers. Follow our guide to use VLANs on FreeBSD, combine VLANs and VNETs and use VLANs with VNET Jails. Learn useful tricks with many exemplifying instances.

FreeBSD Jails – a well-known feature that has become core to many excellent tools on FreeBSD such as the Poudriere package builder. Jails offer process and file system isolation, but for a long time they did not offer very satisfying network isolation. Learn how to isolate networks, how to test potentially hazardous firewall changes and how to do proper jail networking.
