@phant Hello! Thank you for your suggestions. For dpdaction=clear, because this project was recently updated to use Libreswan 5.0 (from 4.15), that option is kept in the configuration for backwards compatibility with the 4.15 version (for example, users may choose to downgrade to 4.15). It may be removed in a future update in this project.

For allowipv6 = auto, this is a new option in Fail2Ban 1.0. Because this project supports a wide range of Linux distributions, some may come with an older Fail2Ban version that does not support this option. See packages for Debian and Ubuntu, for example.
