Your router ([Linux]) sees everything but not a box ([Windoz]) behind it:

Possible causes:

 1 the [Windoz] box might be missing a default route to [Linux]
 2 the [Internet] don't know how to send packets to [Windoz] because:
   a, it has a private network number
   b, 192.168.10.1 don't know the route to it

Remidies:

 1 add the default route either manually in network->properties->tcp-ip
   or through bootp/dhcp
 2 the 192.168.10.1 is your isp's box? Use source nat or masquerading.
   The quickest fix is probably to install ipmasq on [Linux].
