Phone Reboots When Connecting Openvpn

Q: Why does my phone reboots/restarts when I open OpenVpn when I press the start button on OpenVPN. This problem normally affects Sony Xperia Phones (ST18i,ST15i).

A: We have traced this problem on some faulty ROMs that doesn't properly handle the loading of tun module. This problem actually affects all VPN applications that uses tun.ko including OpenVPN.

Solution: Unfortunately we cannot fix this problem on our side since the problem relies on your phone's OS. So the only option you have right now is to flash a different ROM on your phone that properly supports TUN (Recommended is Cyanogenmod).

VPN Connect but can't load website?

Just reset DNS at Openvpn

FATAL:Linux ifconfig failed: could not execute external program

Ok, so the link for route doesnt work at all, route add and route delete fails, however the sym link for ifconfig to /sbin/busybox does work.
So for route, copied the entire busybox binary to /system/xbin/bb and named it route
cp /sbin/busybox /system/xbin/bb/route
that now works !! Took a reboot and some time for it all to sync up, but now connecting perfectly.
