Anyone aware of userspace application firewalls that be run for a process from cli? No requiring system level configs/packages or root privileges. Something like this: app_firewall --block all --allow www.google.com ./my_untrusted_application Or like this: app_firewall --rules my_employer_network.conf ./untrusted_employer_application Then you can do cool stuff like: app_firewall --block microsoft.com qemu my_dirty_windows_virtual_machine.qcow
