Much like Docker, FreeBSD's Bastille uses template directories with Bastillefiles to allow users to deploy applications in a reproducible, automated way.
This template is meant for a VNET host on a VPS that assigns a block of IPV6 addresses and has rtadv and rtosld support. It's designed to work with Vultr's IPV6-only hosts, and unassigns whatever IPv4 address Bastille gave your machine when you created it with VNET.
Defaults to using DNS64 resolution of ipv4-only hostnames using August Internet's NAT64 servers.
