so far I have tried about 6 different configurations to get the FC v2 to talk with the voxl.  
Just as a simple question 
If I have the voxl connected to the computer via cable and the fc connected by wifi, logging in to ssh root@192.168.8.1    
1.if I run voxl-vision-px4 --debug_udp_recv  I get ,  connected tovoxl-mavlink-server but no messages from px4
2 if I go to qgc analyze tools there is a heartbeat   (190 heartbeat 2.0Hz)
I am not able to connect to qgc unless I use the usb cable to FC v2
I have tried the FC v2 telem1 and telem2 and switched the rx/tx with no good result

Any direction that I should be looking would be helpful

changing to j11 and px4_uart_bus": 12, for J11 connection brought the voxl alive  Looks like I can move on to the openvpn brain storm.

Nice work locating that setting, agreed it's not obvious to locate all of this info... Although this is VOXL2 documentation, the graphic here might be helpful to see the plumbing:
