The ovpn(4) is loaded, but the output from ifconfig tun0 for world and kern= el built without INET support reveals that tun(4) is used instead of ovpn(4): tun0: flags=3D1008043 metric 0 mtu= 1400 options=3D4080000 inet6 2001:yyy:xxx:c2:2::1 prefixlen 64 inet6 fe80::1265:30ff:fe7a:9509%tun0 prefixlen 64 scopeid 0x4 groups: tun nd6 options=3D21 Opened by PID 2262 Client config file is 100% compatible with DCO and while running the same OpenVPN client config on system with dual-stack support enabled everything = is fine and tun0 belongs to group:ovpn. For the test OpenVPN 2.6.14 version was used at both ends, installed from the same openvpn-2.6.14 package built in = own poudriere. --=20 You are receiving this mail because: You are the assignee for the bug.=
