Hi,
I am trying to implement UAG per app VPN in cascaded mode but cannot seem to get it to work.
All tests as described in the on-line doc are green but still the tunnel won't open when I try to access internal resources.

and the tunnel connects successfully on the client

But pinging internal resources produces an error:

I can ping the ips from both the outside and the inside tunnel apps
Outside while ping is running

Inside

Any idea what I could be missing?
