   This question is probably general, but the particular case I am working   
   on uses Draytek Vigor ADSL routers (with built-in VPN support) and   
   networks using machines running various versions of Microsoft Windows.   
   Each network has a single external IP address and uses NAT.   
      
   The requirement is to VPN a workstation, which is connected to its own   
   local network, to a remote network. However, both the local network and   
   the remote network use the same address range (192.168.0.x actually),   
   and specific addresses are duplicated; in particular, 192.168.0.1 is the   
   main file server on each of the networks. There is no difficulty if the   
   local network uses a different address range.   
      
   Once the VPN is established, address 192.168.0.1, for example, becomes   
   duplicated and ambiguous: is it the local file server or the remote one?   
      
   Is there any way to get round this problem without having to reconfigure   
   either network?   
      
   Best wishes,
