In this case, you forgoto the return routes for the network. You can supply this in two ways:
- Define for the machine (for example ) a route for the network via the machine.
- Define for the machine (for example that its default gateway is the machine.

In the other network ( you must have to do it the same way. You will have to make routes or define default gateways that know how to go to the network.

Hope this helps
