Do you get an error mesage on the XP client? Do you have a VPN client installed on your machine (this will break native IPSec), or did you have one installed before?
Basically, for Windows XP and PSK, the following settings need to be done: - Networking: Type of VPN = L2TP IPSec VPN - Security: *Disable* "Require data encryption" - Security: set PSK in "IPSec Settings"
during our testing at various clients, we found that the most common problem is a disabled native ipsec service. If you have or had installed an IPSec client, your IPSec service had been disabled during their install routine.
In order to activate it again, do a right click on 'My Computer' and select 'Manage'.
Now the 'Computer Management' Window opens. Expand 'Services and Applications' in the left pane and select 'Services'. You will now see all Windows services on the right pane.
Search for 'IPSEC Services' and see if it is disabled. If yes, change the startup state to 'Automatic' again and start the service.
Hi everybody, yesterday i got L2TP over IPsec working using the native XP-Client. Nonetheless at the moment it works only in a non-NATed environment what is not acceptable for my setup. Anyway if there is interest so far i can post a brief how-to with my configuration. Another point is that the predefined connection-type MS L2TP client on the ASL uses a PSK but i want to use X.509-certificates for authentication. In the handbook i read that this predefined connection type uses a standard-policy. To create my own connection type i need to know what concrete policy settings i have to use. Does anybody know? Still working on this issue, Jan
