+
+## motivation
+- i couldnt find a single repo/collection/terraform provider/api that let me assign and enable lan interfaces
+- i decided to create one mself
+- opnsense api does not let me do it, it just replies with: controller not found
+- but /conf/config.xml has the answer.
+- however for phisical interfaces its the god damn conf.rc
+- my opnsense runs in a vm, so it really doesnt matter for me
+- i just add the interfaces via libvirt and all i need to do is to enable them, given the /conf/config.xml method
+xml has the answer.
