Cisco L2TP client not connecting over IPSEC

I've managed to bring up the IPSEC tunnel between a cisco router to libreswan on linux in AWS cloud. However i'm unable to successfully connect L2TP over the tunnel. I'm behind ISP NAT, hence the 192.168.21.2 on the public interface, and vpn ip masked as google's dns for security reasons
