I'm on Day 4 trying to figure this out and I'm now at a point where it is beyond my level of troubleshooting.
This is an extremely EASY request for configuration setup....or so I thought.
All I want to do is connect three remote VPN clients to my ASA using L2TP over IPEC and all three clients will be using Windows 7.
Here is the configuration of my ASA:
ASA Version 8.2(1)

When connecting from Windows 7 clients I get a Error 789
I've done an exhausive search on this error message and I have checked for everything people have listed including:
- Make sure "IPsec Policy Agent" and "IKE and AuthIP IPsec Keying Modules" services are running (Check, and set for Automatic)
- Modify registry to allow NAT Traversal with AssumeUDPEncapsulationContextOnSendRule=2. (Check)
- Check that pre-shared key is correct. (Check)
- Check Windows 7 FW (Check, nothing is blocking)
I can ping the outside IP address (xxx.90)
My initial thoughts have always been some access allow that is not being set. When client tries to connect, it's like the ASA doesn't even see it.
Any help would be appreciated.
Thanks,
Lee
