Hmm, the packages were obviously RETURNed by the line mentioned to the
global root "catch all" rule and thats exactly what should normally
happen.

In the end I neither want the packages to be dropped nor rejected but
returned instead for the inspection by other chains, but I will only
switch back to RETURN after if I've found the origin for the echo
replies.

So for now, I am quite happy with both DROP and REJECT, thanks :-)
