Re: [Openvpn-users] Strange DCO && UDP problem

Yeah there is definitely something wrong with dco driver behavior on that Windows machine. Looks like some TCP packets (running over UDP tunnel) got lost? There is more we could do to look into it, but I need some time to prepare necessary steps. Meanwhile it would be nice to test from a different

Re: [Openvpn-users] [ext] Re: Strange DCO && UDP problem

I checked the logs you've sent to me in private and data channel params are identical in both dco and non-dco cases. It would be nice to get the logs from the driver when you get admin access to the Windows machine. Also would be interesting to know if this is reproducible on more than one Window

Hi Stella, Just a heads-up. I assume you use Mullvad. I downloaded mullvad ovpn profile and was able to reproduce this issue - no error in openvpn or driver log, but no traffic flow. I'm looking into that. to 9. helmik. 2023 klo 7.19 Stella Ashburne (rewe...@gmx.com) kirjoitti: > > Hi > > I down

This concept is originally from Android VPN API, which provides a way to "protect" socket so that data sent through this socket will go directly to the network and will not be forwarded through the VPN. OpenVPN3 has been influenced by Android VPN API. It also has a mechanism to ensure that data se
