Yes, it is.

The concept of FIBs looks clean and applicable but setfib works on newly
started process, and I would need to do something like apply it to
packets coming from an interface.

I've found previous posts on "policy routing" with ipfw
(http://lists.freebsd.org/pipermail/freebsd-security/2004-April/001839.html)
but this is probably not what I need; I would need that packets
generated as a response to incoming packets go to the same interface as
the incoming packet. Or are you thinking of hard-coding client addresses
in ipfw rules so that packets going to specific IPs go to a specific
interface?
