Windows, v2.6 and DCO

Post by luckyj » Tue Apr 25, 2023 9:11 pm

So, I'm looking at version 2.6, latest 64 bit community version 2.6.3 on Windows (upgraded from 2.5) and just trying to figure out how to know it's using DCO. The documentation says 2.6 will use DCO by default.

The DCO network interface exists, but doesn't get configured with an IP. Windows is still using the wintun interface that I previously had configured.

If I change the client config to windows-driver ovpn-dco, I get "Option --windows-driver ovpn-dco is ignored because Data Channel Offload is disabled".

Is there a way to check, or am I just not understanding how this all works? I've been looking around for a couple days and came up short. Finally decided to post here.

Oh brother... just found out it was because of comp-lzo no in the client config. :(
