Cisco PIX 7.2 - Setting up L2TP RA VPN around Static L2L VPN Tunnels

Asked by reighnman in IPSec Security Protocol, Virtual Private Networking (VPN), Cisco PIX Firewall

Cisco PIX 515
Pix Ver: 7.2(4)
ASDM Ver: 5.2(4)

I recently upgraded our PIX from 6.3 to 7.2 in order to do L2TP/IPSEC VPN with our Windows Clients.  Currently we have 4 site to site static VPN tunnels which were all converted during the upgrade.  After installing ASDM, I ran the ASDM VPN Wizard following the instructions from the Cisco website for L2TP/ISA setup ( http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_configuration_example09186a00807213a7.shtml ).  You can watch me running the wizard here ( http://screencast.com/t/VDvMYV5E1 ).  

When I attempt to connect from a remote Vista or XP machine, I get 'Error 789: The L2TP connection attempt failed because the security layer encountered a processing error during inital negotiations with the remote computer.'  Watching the log in ASDM, I see PHASE 1 COMPLETED followed by QM FSM error (P2 struct &0x2dbce00, mess id 0x1)!, Removing peer from correlator table failed, no match!, Remove peer from peer table no match!.

When I searched the Cisco site for QM FSM error, only thing it mentioned was an issue with sequence numbers, but mentions that there can only be 1 dynamic map for each interface which I think may be part of the issue.

Full running config and debug attached (txt).  Modified external ip-addresses and passwords in the config for some security.

Here is a snip of the config for the crypto section, any help would be appriciated.Start Free Trial
