> Install and turn on OpenVPN DCO to enhance Access Server's performance. This module offloads the data channel to the Linux kernel.

OpenVPN as 3.0.2 requires OpenSSL 3.4, which is only supported by version 9.7. However, after installing OpenVPN as, I get the following error: “OpenVPN data-channel offloading was requested but failed to activate. This typically happens if there is a configuration option that is incompatible with DCO or if the DCO kernel module could not be loaded.”

How do I install kmod-ovpn-dco? Red Hat Enterprise Linux supports it, but how do I enable DCO on RockyLinux 9.7? Thanks!

How did you get it working on RHEL9? What package(s) did you install? What is the **exact** kernel module name?

I’ve tried searching for _dco_ but found nothing, so we would require a bit more information on this. But if the kernel module is available by default in RHEL, then it’s available by default in Rocky as well. Hence, if there are other packages installed that provided that module, then we need to know what package and from where.
