# ovpn(4)

OpenVPN DCO driver

## NAME

**ovpn** – OpenVPN DCO driver

## SYNOPSIS

To compile this driver into the kernel, place the following lines in your kernel configuration file:

**device ovpn**

Alternatively, to load the driver as a module at boot time, place the following line in [loader.conf(5)](/loader.conf/5.md):

```
if_ovpn_load="YES"
```

## DESCRIPTION

The **ovpn** device driver provides support for OpenVPN DCO. DCO, or Data Channel Offload, moves the OpenVPN data path into the kernel. This can improve performance.

The **ovpn** interface is created automatically by the OpenVPN daemon. It requires no configuration other than that done by OpenVPN.
