With an Ethernet User Node, you can define:

Custom port selection... and error injection with the Advanced... button.
Select default routing that were configured for the test server.
Select the Next Hop IP Address instead of using the test server's default route.
The Outbound Traffic Port to disable the normal routing function and to force packets out of the selected interface.
