Some components are related to or dependent upon each other, meaning that modifying one modifies the other too. If modifying a component affects another component, the status of this related component changes to Invalidated in the Configuration tree. ZMC automatically handles related components and all actions (Commit, Reload, and so on). Just select the Apply action for the dependent components checkbox in the confirmation dialog of the action.

When reloading or restarting a component related to the Packet Filter, the skeleton of the Packet Filter is automatically regenerated. See Appendix A, Packet Filtering for details on generating skeletons.
