About the module of NX network

hi.
1、we make one product of NX,have a question about the network。
2、we use one USB 3.0 channel ,connect the 5G module; add NX own ethernet control。
3、we want through USB adpter 5G connect World Wide Web,through the ethernet connect intranet. How to realize simultaneous connection??and They don’t affect each othe。

I think you can just remove the gateway setting of your wired ethernet, since it is not going to the outside.

Also, this issue seems not directly related to jetson. This seems a general one for any kind of devices.

thank you very much。
