The original address *is* the real address. NAT breaks IP's design and
is a very mixed blessing. NAT isn't needed nor used with IPv6, and
being in IPv4's twilight years, an argument predicated on NAT is not
very convincing.
I feel that describing the patch as routing is misleading, as it
performs only outbound link selection. It fosters an expectation of
bi-directionality, and that is not the case. It will often result in
asymmetric routes.
Is it possible you are trying to solve a problem which has already been
solved, for example by IGP?
