Cannot connect to VNC server over openvpn

[spacecase-25]

As the title says, I am having trouble connecting to a VNC server on my VPN (10.1.11.2) from my iPad client, also connected to the vpn.  I can connect to the VNC server if the iPad is on the same LAN, but if I use the VPN IP address to connect I cannot. 

I do have inter client communication enabled.  Do I need to set up some other firewall rule? 

Thanks.

EDIT: Just got home and tried connecting from my laptop, and it works, both from my LAN and tethered to my phone & connected to my VPN.  So that's fun... must be something to do with the iPad (of course it "just works" on Linux)

I had to manually push a route to the vpn subet.
