I needed to replicate a Juniper SRX firewall to create and test a BGP config for a customer. I could have done this in GNS3/EVE-NG or some other virtual enviornment, but I find that Vagrant/Libvirt gives me the most usability when trying to reuse a setup over time, such as for automated testing. So with that goal in mind, I needed to create a vagrant box of Juniper’s vSRX firewall, but specifically for use with libvirt.
