[solved] DCO (Data Channel Offload) working?

[Bob.Dig]

Is there a way to see if DCO is actually used? I enabled it on some tunnels to a vpn provider and the tunnels do work. Or could it silently fall back? Not sure if I look in the logs.

It isn't an option that is negotiated, it doesn't know or care if the remote side does DCO. It only changes how the system locally handles crypto. If it's enabled, it's used.
