yes, carp is layer 2 load balancing. As soon as you get to layer 3,
a router port, all layer 2 stuff stops. Or to be more technical you
must be in the same layer 2 broadcast domain/segment for this to work.

Off hand I do not know if carp has the ability to do this, I do not
think so though. What you are looking at here is a sticky nat type thing
or a cisco local director type solution, it can be configured to be
sticky. I also think IPF nat can do that, PF I have not used.
