Occasionally we get a customer who needs to add a network to Network Performance Monitor that is not reachable from their main network. This type of connectivity is shown in the figure below.

Making this work is not very difficult as long as you follow a few rules.

 

  1. As always, the networks cannot share any IP address space.
  2. Don't count on the default gateway alone to define any networks except the ones directly attached to your server.
  3. Use the route add command in a Windows prompt to add all networks you need to manage.
  4. Do not connect the two networks. If you add a router later the ability to route between the networks will break this solution.
