I use OpenVPN (with v1.28.9051 MIPSR2-beta22 K26 USB vpn3.6 on RT-N16) and I set "Start with WAN" flag: sometimes openvpn doesn't start when I light on my router.
I get these from log (after kernel messages):
Jan 1 01:00:52 rt-n16 user.info kernel: tun: Universal TUN/TAP device driver, 1.6
Jan 1 01:00:52 rt-n16 user.info kernel: tun: (C) 1999-2004 Max Krasnyansky <moc.mmoclauq|kxam#moc.mmoclauq|kxam>
Jan 1 01:00:52 rt-n16 user.info init: VPN_LOG_ERROR: 136: Creating tunnel interface failed…
If I start VPN manually all works normally.
Do you have any experience about this problem?
