| + | # Data Channel Offload: non-Linux platforms |
| + | |
| + | ## Windows |
| + | A kernel module has also been developed for Windows, namely *ovpn-dco-win*. |
| + | |
| + | It is a device driver implemented in kernelspace that substitutes all previous drivers used by OpenVPN (i.e. tap-windows6, wintun, etc..). Differently from the other drivers, ovpn-dco-win uses the Windows Kernel API to also implement crypto operations, thus allowing the driver to process data packets entirely in kernelspace, similarly to ovpn-dco for Linux. |
| + | |
| + | The main limitation of ovpn-dco-win is that it only supports client/p2p mode, while server mode is not available. This decision was made due to the fact that there is less and less demand for running OpenVPN server on Windows. |
| + | |
| + | The ovpn-dco-win source code is currently available at the following repository: https://github.com/OpenVPN/ovpn-dco-win |
| + | |
| + | ## FreeBSD |
| + | The FreeBSD community has shown great interest for the DCO model and so they also implemented a FreeBSD kernel module. |
| + | It is expected to be a drop-in replacement for ovpn-dco on Linux, thus implementing the same feature set. |
| + | |
| + | The originally proposed change (now merged) can be found at: https://reviews.freebsd.org/D34340 |
| + | |
| + | DCO will be shipped starting with FreeBSD 14 (to be released yet). |
