I agree, but we have to find out, what is wrong...

Technically, some of the routes point out to the same interface,
but a different IP (like x.x.x.5), and some point out to the wan interface.

Here's the small network layout again:

inet ------ wan:rtr1:lan ------ rtr2 ------ wan:host
                     x.x.x.1                y.y.y.1
