Need help with setting up policy for Client-to-Site VPN

So I'm self-studying PA and setting up a simple VM lab for myself, just to get the ideas of how all this work. Everything is fine until I try to set up the GP VPN. The thing is whenever I use a Client connected to VPN, the PC in LAN lose its access to internet, and I can't ping between the Client and LAN PC. I think the problems is in Policy, but I'm not so sure. Any ideas how should I fix this?
