For years, up through Buster, I have had a nice setup with virtual machines on my laptops, with firewalling provided by shorewall and rules I have added over the years. As I move from network to network, the firewall is reconfigured, and the VMs continue to work. I also have scripts that detect my home networks, and re-do the firewall for use on the home network.
Now, with Bullseye, I seem to be hitting a brick wall. Something -- libvirt?? -- is mucking with my firewalling and breaking the virtual internal networking. What is the preferred way of running libvirt on a laptop? I do not *have* to have shorewall, but would like some sort of firewall tool. -- Does anybody read signatures any more? https://charlescurley.com https://charlescurley.com/blog/
