@fabianfrz Thanks for your review!

[fabianfrz]

@fraenki you may want to migrate some code to the *Base methods, to reduce the size of the controller.
It makes most actions one liners except some special ones which do need a more specific behaviour.

[fraenki]

@fabianfrz I'll consider this for a future release, the changeset is already quite large for a minor release.

@fichtner Please merge for OPNsense 18.7.8.

[fichtner]
