It's kind of hard to understand. There are multiple "25" metrics. Which one does it use? Lan or Wan? Microsoft Windows XP [Version 5.1.2600] (C) Copyright 1985-2001 Microsoft Corp.

The only routes that aren't exactly duplicated are the 192.168.1.101 and 192.168.1.102 routes which are routed as loopback addresses. Since 20 wins over 25, 192.168.1.101 will be the default interface.

You can chose which interface to use:- http://support.microsoft.com/kb/894564 The only entries that are particularly relevant are the top four. The top two determine which interfaces are used for traffic sent to your router, the next two are for local traffic to PCs on your local network. In both cases interface 192.168.1.101 is being used since the metric is 20 which is better than 25. Just ignore the rest, it is only there to confuse you:)
