Ok. I manage some gateway that handle two or more connection to ISP; i
balance traffic between routes, and sometimes via policy routing i
'bind' some traffic to some interfaces (forward traffic, so PREROUTING
in mangle).
This time i needed to bind local generated traffic, because one of the
two line use dynamic IP and the service i use need static IP (they have
some ACLs).
Initially i've simply applied the same policy i was used to, but does
not work (clearly, PREROUTING is for forwarded traffic, not or local
generated one! Stupid me! ;).
Then i've tried with OUTPUT, but with the same result.
Now i'm using explicit routing, and clearly works. But i was curious,
so i've posted here.

Do you mean this?

I've no kernel 4.4, but i'm using load balancing with:

and i suppose is a similar concept...
