(and boy that is not especially easy or obvious; you have to 'Plan' to add an artifact...)

Not sure what you mean here. Care to elaborate?

If I recall, the FMS runs at 10.100.0.x addresses. The robot never needs to send or receive packets to or from the FMS. The DS takes care of all of that communication. I don't recall what the router configuration on the field is (if it hands out a default gateway that is needed or if it broadens the subnet mask). Based on your original post I would guess it's the latter, but I can't say for sure. The DS should always be configured for DHCP so it will always do what the field requests vis-a-vis network configuration. In your proposed configuration you have to react manually to any field configuration change.

It is a work-around to an actual problem that teams obviously are dealing with. Thanks for sharing!
