So onan is using reknaw as its default gateway?

Okay, so you have a router here that isn't either of these systems.  
How is onan supposed to reach it?  How is onan supposed to resolve the
name of the other machine?  [It seems to be doing so; therefore, I
assume that you have this part configured properly, but you didn't
really show enough of the topology for others to follow.]

You could theoretically do it, by running separate subnets on the same
link, but you'd have to be careful not to leak any of the private
addresses via your gateway router.
