Hi
Was anyone successfull in setting up an L2TP/IPsec tunnel through NAT-T against a Windows 2008/ R2 RRAS server? I am using an 881 router and the layout is someting like this:
Client -> 881 -> NAT -> internet -> Windows 2008 RRAS
The tunnel goes form the 881 to the Windows server (not from the client...).
Thanks

Roland,
L2TP client-initiated tunneling allows the client router to initiate Layer 2 tunnels.
Check this out:

Hope it helps.

Hi Federico
Thanks for your help! Much appreciated.
In my case this should be transparent to the client - I would like not to initiate the connection from the client.
Does that makes sense? I am considering L2TP because Windows 2008 R2 doesn't support IPSec tunnels through NAT (2008 R2 being the responder and the Cisco router the initiator of the IPSec connection).
Regards
Roland

cisco sends L2TP Start-Control-Connection-Request (SCCR) 3 times and after that stops.
its happens in a loop.
no Event logs in Windows RRAS
on Windows server with Netmon i cann see that packets from cisco arrives.
I can connect to windows RRAS with windows client (like a test) w/o issues.
