and nothing, ping waits and no reply, Ctrl+C

with such a simple setup rules based routing should not be involved, kernel should figure it out, right?

you specifically said to send that packet to an interface on the wrong network, of course, its not going to get through, unless there's an external route from that network to the destination. I'm presuming there's a router somewhere else between your 192.168.2.0/24 network and 10.5.6.17, that would enable those ping -I em1/2 commands to work. note that the recipient of the ping needs to have a route to get back to the source, too.
