Same problem on a Samsung Galaxy S3 fw 4.04. Openvpn Settings 0.4.12
Seems to be a problem with how Openvpn calls ifconfig. If I connect and then in 
a terminal do su ifconfig tap0 192.168.52.57 (or the address that openvpn 
reports it has connected to) I can ping the VPN gateway but that's it.

The problem must have been that I somehow fumbled  the installation of Busybox. 
I went with the default and let it install to /system/bin instead of xbin. When 
I checked ifconfig and route in /system/bin they were links to toolbox instead 
of busybox. After much googling I pieced together the following procedure which 
fixed the problem for me. I don't presume to take any credit for this, the 
solution is around  there. I just had to adapt it to my installation. Here it 
is:

su
mount -o remount, rw /system
ln -s /system/bin/busybox /system/bin/ifconfig
ln -s /system/bin/busybox /system/bin/route
mount -o remount, ro /system

Error above, there should not be spaces after the commas in the mount commands.

I realized I forgot to mention that I had to delete the old links before making 
new ones. WIth that the complete procedure becomes:

su
mount -o remount,rw /system 
rm /system/bin/ifconfig
rm /system/bin/route
ln -s /system/bin/busybox /system/bin/ifconfig 
ln -s /system/bin/busybox /system/bin/route
mount -o remount,ro /system

The last bit is there to write-protect /system again so you don't mess up more 
than necessary. If your busybox is installed elsewhere the paths need to be 
adjusted accordingly. Take care, not having /system write-protected makes it 
easy to mess up
