We have a working configuration for L2TP-IPSec connection from a native Windows XP client to the ASA 5510. When trying to set up a connection from a Windows 7 client, the connection fails with the message that all SA proposals are unacceptable
Is this coexistence possible, and what parameters would I have to change to get this working. I have understood that the Windows 7 client requires som higher security proposals, but have not found what these are. And at the sam time we are concerned about not destroying the VPN connection for our existing XP clients.
Any help would be appreciated.
Thanx in advance
