Without IPv4 the local Tunnel-Interface has no addresses. On Ubuntu 14 the Network Manager reports a ""Incorrect Configuration"" and aborts. Background: Friends and customers have only IPv4 address space available. With a OpenVPN-based solution I want to tunnel a IPv6 prefix and a ::/0 route to this client(s). The previous installed IPv4 default route will not override by a default route of the IPv6-only OpenVPN connection. It's a bug or a feature? ;-) Thank you for a answer. -Markus",Bug / Defect,closed,major,,Generic / unclassified,OpenVPN 2.3.8 (Community Ed),"Not set (select this one, unless your'e a OpenVPN developer)",notabug,IPv6 Only Tunnel,
