Another idea from colleague, is to bind the source address of the socket to
the address of the desired netwrokr interface.
While it doesn't guarantee anything, he said that in practice the kernel
routed the packets through the desired network interface.

Sorry. My default was not 'send to all'. Now posting to the list as well.

Assuming you want the paths to be selected dynamically based on load, you
can use iputils2 'ip route' to create a multi-homed routes. You will not

raw socket might help. It will bypass routing, but it will also
bypass the UDP stack...

You may also try changing the routing rules:

The other way is to do normal packets, and modify the kernel routing
behavior in between (like with 'ip rule'...) - your
use the SO_BINDTODEVICE setsockopt.

this is raw ethernet. i want to use the udp stack,
You can add capability of raw socket to the executable, hence run as
non-root.
Since what you're asking means potentially send illegal (unrouteable) IP
packets, I guess that indeed the kernel will require special privileges to
enable you to do that.
As I said, you can mitigate that with
