This is arguably a Windows question, but it must be applicable to a lot of people.
When we go to the shop floor to connect to a machine network, we use our wireless adapter to stay connected to resources like network drives and the Rockwell activation server, and we use another adapter (usb or built-in) to plug into the machine. An ethernet gateway address isn't usually needed on the machine network.
The newer lines in our plant have more complicated networks of PLC's linked through NAT's. Sometimes I need to go online with a few PLC's at once and the NAT's are configured with a translation for the laptop. As long as my laptop has the NAT identified as a gateway, it'll work great. I can go from the Private side of one machine NAT and connect to the other PLC's as well, using their Public addresses.
BUT, when I set a gateway address for the machine network on the laptop, most of my wireless resources stop working because DNS requests are going unanswered because the laptop is picking the machine gateway as the address to use. If I remove the gateway entry, everything works fine on the plant side, but now I can't reach the networks on the Public side of the NAT.
So the question is, is there a correct configuration in Windows (7) that supports two different gateways on two network adapters at the same time? It seems like there must be but I am not having any luck.
Thanks.
