IPSec Remote Access VPN with different public IP than wan interface IP

I succeeded to configure Remote Access SSL VPN with public IP that is different than wan1 interface IP as wan1 interface has private IP, and I did that by using virtual IP that redirect that public IP to private IP of wan1 interface.

I tried to do the same with IPSec Remote Access VPN, VPN connection gets established successfully, but I can't connect to inside private network that I set in VPN configuration. I used the wizard for VPN configuration. I tried configuration with enabling/disabling split tunneling and enabling/disabling NAT for VPN IP policy without any success.
