That doesn't naturally translate to > 'LAN-Verbindung 3'. we downloaded and smoothly installed https://github.com/openconnect/openconnect-gui/releases/download/v1.3/openconnect-installer.exe I cannot preclude an earlier manual installation of th eopenvpvn TUN/TAP driver, though. We had done some experiments with earlier versions of openconnect-gui. > It is 'LAN-Verbindung 3' which is displayed in the control panel if you > go to the adapter settings? If you rename it there, do things change? yes, renaming it to "TAP" results in successful setting of the IP address as shown by ipconfig. > Is it possible to work out what name *does* work with 'netsh' for this > device? ------- netsh show with old Adapter Name "Lan-Verbindung 3" -------------------- C:\Users\martin\Documents>netsh int sh int Verw.-status Status Typ Schnittstellenname ------------------------------------------------------------------------- Deaktiviert Getrennt Dediziert Cisco AnyConnect Secure Mobility Client Connection Aktiviert Getrennt Dediziert LAN-Verbindung 3 Aktiviert Getrennt Dediziert LAN-Verbindung Aktiviert Getrennt Dediziert Drahtlosnetzwerkverbindung C:\Users\martin\Documents>netsh int sh int "Lan-Verbindung 3" LAN-Verbindung 3 Typ: Dediziert Verwaltungsstatus: Aktiviert Verbindungsstatus: Getrennt ------- End of netsh show with old Adapter Name "Lan-Verbindung 3" -------------------- - Use Network settings (ncpa.cpl) to rename adapter to "TAP" ------- netsh show with new Adapter Name "TAP" ------------------- C:\Windows\system32>netsh int sh int Verw.-status Status Typ Schnittstellenname ------------------------------------------------------------------------- Deaktiviert Getrennt Dediziert Cisco AnyConnect Secure Mobility Client Connection Aktiviert Getrennt Dediziert TAP Aktiviert Verbunden Dediziert LAN-Verbindung Aktiviert Getrennt Dediziert Drahtlosnetzwerkverbindung C:\Windows\system32> C:\Windows\system32> C:\Windows\system32>netsh int sh int TAP TAP Typ: Dediziert Verwaltungsstatus: Aktiviert Verbindungsstatus: Getrennt -------End of netsh show with new Adapter Name "TAP" ------------------- So looks like it's really all about the adapter name chosen by some Windows magic. In my Opinion, setting the name explicitly to something clear like "TUN/TAP openvpn/openconnect" would help anyway. You could tell adapters apart much easier then. BTW, manually calling openvpn's %ProgramFiles%\TAP-Windows\devcon.exe install "addtap.bat" (which in turn calls devcon.exe) results in another "LAN-Verbindung 3" (the name was no longer occupied because of the above rename). > But looking at your registry files, it definitely looks like that's > what it's called.
