Title: OpenVPN Client Device mode not working correctly
Post by: Vonguru on January 23, 2018, 10:02:52 am

Hello,

When I set my device mode in my OpenVPN client to tap, it appears to still be set to tun based on the following error message on the OpenVPN server side: 

Code: [Select]

WARNING: 'dev-type' is used inconsistently, local='dev-type tun', remote='dev-type tap'
Thanks,
Von

Maybe you can only run in tap mode over UDP?

You need to have the same tunnel type for both ends; the client needs to request what the server offers.

https://community.openvpn.net/openvpn/wiki/Openvpn23ManPage says: "You must use either tun devices on both ends of the connection or tap devices on both ends. You cannot mix them, as they represent different underlying network layers."
