Site2Site ipsec with other side is dynamic from ISP

Guys,

Ive been digging to the internet and there are lots of tutorials and videos for Site to Site ipsec between 2 MT routers with other side is dynamic/Nat’d ip address from isp and the other side is static. But all of them doesnt work.

Does it really work if the other side is having a dynamic ip and the corporate office is static .
