yes, it does work when I specify the correct address with ping, but
doesn't when I don't specify an address.

Nope. I did it in this sequence:

 1. ping with forced source address -> success
 2. ping without forced source address -> failure

Some important programs don't have an option to specify a source
address...

I always use -n because I don't have DNS on that network anyway, and it
goes faster, and is more true, too.

The routing table does not show any appearance of the wrong address,
only some mac addresses for hosts, and some "link#n" entries for
directly attached networks.

Best,
