What version of the OpenVPN client does this WAN license install? Specifically, I’m wondering if it supports Data Channel Offload as stated here:
The client does not need to use DCO to connect to a server that uses DCO. With only one side doing DCO, there is already a performance benefit. However, it is best if both sides use it. The following clients can use DCO on the client side, although it will have to be enabled separately in the client.
Clients with DCO capability:
- OpenVPN3 Connect for Windows (as of 3.4.0).
- OpenVPN3 Linux client (check with the community documentation for the supported Linux operating systems).
- OpenVPN 2.6.0 or newer (check with the community documentation for the supported Linux operating systems).
- OpenVPN GUI community client for Windows (refer to community downloads).
