Yes, this is always an option. But the problem is that current
physical topology does not allow for such connection. CISCO is
directly connected to the routing FBSD box and the x.y.z.102 box
is cascaded several time below the level of the FBSD router (switching
hubs are cascaded). Of course, I could change the topology but I
really
rather not do so.
What I think would really interesting to know is how to do the baroque
routing you meantioned. I agree that putting x.y.z.102 on the 192.168
network is topologically incorect, but c'est la vie, it just needs to
be
done. As you remember from my original post, i got things routed a bit
when is split the /27 network into two /28. I got it routed from local
box to FBSD router and back, however could not go past the FBSD
rounter. I think the problem might be either on FBSD routing rules
or with CISCO not knowing that /27 was split into two /28
