I have a Cisco ASA 5505, with IPSec VPN configured. Everything was working just fine, until I needed to disable Split-Tunneling. Basically, we need to have all computers connected to the VPN to have their internet connection go through the ASA. So, the problem is, now that I have made the changes to remove split-tunneling my users are unable to access the local LAN, so the VPN is working, and the traffic is going through ASA, but we are not able to connect or even ping any local LAN servers. Below is my running-config file, please let me know what I did wrong and what am I missing.
Thank you for help.

Hi
I see that you're missing the may exemption.
Try that:
access-list nonat extended permit ip 192.168.1.0 255.255.255.0 10.250.250.0 255.255.255.0
nat (inside) 0 access-list nonat
Let me know if that worked
