Issue is resolved by using correct IP address and followed steps mentioned in https://github.com/hwdsl2/setup-ipsec-vpn/blob/master/docs/clients.md#windows-error-809
After correct configuration was getting error 809
Error 809: The network connection between your computer and the VPN server could not be established because the remote server is not responding. This could be because one of the network devices (e.g, firewalls, NAT, routers, etc) between your computer and the remote server is not configured to allow VPN connections. Please contact your Administrator or your service provider to determine which device may be causing the problem.
