Hi Anvar,


Yes it's possible: you should use a dynamic crypto map on the side where the static ip address is configured.


In this case you can initiate the IPSec connection from the client side only that has the dynamic ip address, as the server side cannot be configured with a peer ip address (it's dynamic).


You will have some additional info here:

Loog for reverse route injection (RRI).
