If memory serves me, the 192.168.0 network addresses like the 10.xxx
address are not routed by default. They are expected to be a private not
routed network. So unless you are using a NAT router or modify the
router setting to pass those IP addresses it should not work. This is
covered in one of the network RFCs.
