Hi,

I have configured my ASA, which is already setup for site to site VPN's and Client access VPN using the Cisco Client, for L2TP/IPSEC VPN access. However, I am unable to connect from a Windows client. Below is my config and I've attached a copy of the debug. Please could you help.

what i suggest you is to have a look at the following nice example that configure l2tp/ipsec on asa with win pc it will guid u step-by-step and check it with ur config as well

http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_configuration_example09186a00807213a7.shtml

good luck

if helpful Rate

Having gone through the config the only changes I made to my config were:

To add 'vpn-tunnel-protocol l2tp-ipsec' in group-policy DfltGrpPolicy attributes

and to remove 'isakmp ikev1-user-authentication (outside2) none' this now results in 'Tunnel Rejected: Conflicting protocols specified by

tunnel-group and group-policy' in the debugs.
