I had encountered problem on IPSec VPN Client with ASA 5525-X version 9.1 and above.
Cisco ASA 5525-X was setup as VPN Gateway. I was using Cisco IPSec VPN Client, version 5.0.07.5410.
I could successfully login to VPN. After login to VPN, I was not able to access Internet, for example http://www.google.com.sg, http://www.yahoo.com.sg. Split tunneling was disabled.
I also could not SSH or RDP to my devices in Internet.
I tested version 9.1.1, 9.1.2 and 9.1.4, all these versions encountered the same problem.
When I downgrade version to 8.6.1, the problem disappeared.
While ASA on 8.6.1, after I login to VPN, with the same IPSec VPN Client, I was able to access Internet and SSH/RDP to my devices.
No configuration changed on ASA, only ASA version changed.
My Configuration as below (I masked off my internal and production IP):
