I believe that the issue is that you are still using the IPsec client and that it does not support Windows 10. Cisco stopped selling this client in 2011 and the end of support for this client was in 2014. So there is not anything that would have added support for Windows 10 into this client.

To get Remote Access VPN on Windows 10 I believe that you will need to implement the AnyConnect VPN client.

HTH

Hi aswind01011 ,

Here is a thread that you must look into to continue troubleshooting IPSec client on Win10:-

Basic principle remains the same with Anyconnect VPN client i.e. to provide corporate access to remote users. However, unlike IPSec VPN client, Anyconnect works on SSL protocol and has many more features associated with it.

As far as the anyconnect configuration and implementation, this document should address your concerns:-
