Definition of Done: Please mark each item below with ( / ) if completed or ( x ) if incomplete: ( ) The acceptance criteria defined below are met. User story: As a network administrator, I want to be able to opt-out of NM-libreswan's default values and use libreswan's default values instead, so that I can configure VPN tunnels without dealing with overriden defaults that complicate configurations. Acceptance criteria: Given a network administrator is configuring a VPN connection using NM-libreswan, When they enable the property to use libreswan defaults, Then, the connection should use libreswan default settings for all options that are not explicitly set the by the network administrator. Definition of Done: The implementation meets the acceptance criteria Integration tests are written and pass The code is part of a downstream build attached to an errata ( ) Code changes are included in a downstream build attached to an errata. ( ) All required testing (manual and/or automated) passes successfully. ( ) Related documentation updates (if applicable) have been completed.

.The `NetworkManager-libreswan` plugin supports using the Libreswan default values With this enhancement, you can set the `no-nm-default` property in Libreswan VPN connection profiles to `true` to use Libreswan's instead of NetworkManager's default values. This ensures the compatibility with configurations defined for native Libreswan. As a result, you can now, for example, configure subnet-to-subnet tunnels.
