Public bug reported:
According to FW (Fortigate), the connection is established and IP provided - no
problem is logged there.
The L2TP client fails, and "closes connection" 1 sec later.
The same configuration worked fine before 13.10.
Here's the log, (only IP modified)
Please say so if I can help testing this problem.
