Ping Type

Instruct the app to use legacy-style ICMP pings. By default, the app retrieves latency information for a location via an HTTP request to a server node. The app should be restarted after adding this parameter, and it is only available on Windows.

ws-use-icmp-pings

Disable Pings

Valid as of app version 2.16.2. This parameter disables pings, for users who are concerned that the pings may give a distinct pattern to their network traffic while disconnected. You must restart the app after enabling this parameter.

ws-no-pings

Log Pings

This parameter instructs the ping subsystem to log the ping results.

ws-log-pings

OpenVPN DCO (kernel) driver support

The DCO driver was made the default OpenVPN driver in v2.12.1. The following param can be used to fallback to using the wintun driver:

ws-use-openvpn-tun-tap

  • Note that this has changed from ws-use-openvpn-wintun on versions before 2.23.4.
  • Instructs the app to use the user-space TUN/TAP driver rather than DCO for all OpenVPN-based protocols.
  • This param should be added while in the disconnected state. An app restart is not required.
  • This param works on Windows and Linux. It has no effect on Mac.
  • Custom configs will always use TUN/TAP.
  • NOTE: use of the DCO driver requires a minimum of Windows 10 20H1. User will be warned in the installer and app logs if they are on an unsupported version and the app will use TUN/TAP.
  • On Linux, DCO will be active if the "ovpn" module is available and you are on kernel version 6.16 or later. OpenVPN 4.0 will detect it automatically and use it when appropriate.
