Over the years, I've written a bunch of guides revolving around VirtualBox networking features, likefor instance my network & sharing tutorial, how to share over NAT with port-forwarding, and howto configure NAT networks. As it happens, I also happen to use thebridged network functionality, because it's simple and convenient, and seems to work reliably well,with wired and Wireless adapters and whatnot. For many years, there was no trouble, and suddenly, thereis. Bridged networking stopped networking for me on Linux hosts running VirtualBox 6.X. Geddit? Networknot-work. Ho ho. Follow me.
