Mikrotik -> Cisco ipsec tunnel

I have some problems with creation ipsec tunnel between Microtik and Cisco

I suceffully configure ipsec policies and peer. But other side, where is Cisco require what i must connect with address 10.254.xx.xx, but ipsec connects by my real external address.

Where and how can i introduce 10.254 address ?

Can anybody help me resolve this issue ?

Problem solved.

I make vlan to internal interface with needed address. Introduce it on ipsec policy as source address. After this, make a src-nat rules to send traffic to needed lan through created vlan. And, everything works fine.
