You can merge sections and consolidate the rules within those sections. Note that you cannot merge a section with the Service Composer or Default sections. In a cross-vCenter NSX environment you cannot merge a section with the universal section.

About this task

Merging and consolidating a complex firewall configuration can help with maintenance and readability.


  1. In the vSphere Web Client, navigate to Networking & Security > Firewall.
  2. For the section you want to merge, click the Merge (merge) icon and specify whether you want to merge this section with the section above or below.

    Rules from both sections are merged. The new section keeps the name of the section with which the other section is merged.
