Ipsec after dst-nat

Greetings!

The situation is the following:
My ISP gave me a local IP 10.176.13.91 and makes dst-nat to it for all incomming traffic to real IP 188.134.70.123

So I have 10.176.13.91 at Mikrotik router as external address.
I need to create IPSEC connection and I’ve done it - from inner network (192.168.88.0) it works very good, but when I try to connect from I-net to 188.134.70.123, I fail due. As I was said, I need to set an IPSEC connection ID to my reail IP address (188.134.70.123).

Help me please, how can I achive this?
