L2TP/Ipsec how to join another device

Hello everybody,
I have setup L2TP connections for 2 devices: 1 laptop wia windows, and one CCR 1036, both connects to another 1036 on an other site.
Connections works fines, but i can’t ping from the laptop the other Router also connected.
But from the L2TP server i can ping both.

Could you please give me the trick ? :slight_smile:

Thanks a lot
