Hi Cisco Experts,
I'm using a 877w Cisco router as endpoint for L2TP2 tunnels. I use an Microsoft IAS (radius) for the authentication. Until last week, all wwas working fine, but now, when my clients tries to establish an L2TP tunnel, the tunnel is established but after 20 seconds the tunnel is suddenly disconnected.
This is the output for "debug vpnd events" command:
Dec 16 15:33:57.334: VPDN Received L2TUN socket message <xCRQ - Session Incoming>
Dec 16 15:33:57.338: VPDN Tnl/Sn 17533 57 L2TUN socket session accept requested
