How to Deliver Modern WiFi Connectivity for BSD-based Firewall VM? - Piotr Król, LPN Plant Sp. z o.o.

lpnRouter is a product that leverages Xen Hypervisor and Dasharo Secure Firewall firmware to create a virtualized BSD-based firewall with modern WiFi support. BSD systems are well-recognized among the network appliance market. Lack of support for the most recent WiFi specification (e.g. 802.11ac) in BSD limits WiFi cards' usage to older models with lower bandwidth, automatically reducing the user experience and total addressable market. The proposed solution leverages Xen Hypervisor capabilities to create create a small Linux-based WiFiVM being a network driver virtual machine implementing modern WiFi card features. The second VM will be the OPNSense serving as the primary VM with GUI for firewall configuration. The WiFi card from Linux VM will use a bridge as a VIF to the OPNSense, where it will expose as an Ethernet card.

For more info about the Xen Project, which is focused on advancing virtualization in a number of different commercial and open source applications, including server virtualization, Infrastructure as a services (IaaS), desktop virtualization, security applications, embedded and hardware appliances, and automotive/aviation, see: [ Ссылка ] or @XenprojectOrg for more videos.
