Currently, I have solved all my problems, (it seems
so) without adding any routes to the 10.R.R.R router.
I have just added the 193.x.x.x interface to it and I
gave it an address in that interface. This seems to be
What I have learned from this problems is that a
router can only route packets that are coming from
interfaces that it knows. Thus it either has to be a
member of the source subnet or we have to
appropriately translate the addresses via NAT. Am I
Although I have not followed your advice I am very
grateful to you, because you helped me think towards
the right direction. I will also keep in mind what you

Thanks a lot
