Hi!

I am developing a ROS package (ROS Noetic – Ubuntu 20.04), where one of the nodes needs to communicate with the internet (specifically to an AWS service). This package is running on a computer, which has two network adapters, one to a Wi-Fi network and one to a 4G network.

The objective is to use the 4G network to connect to the internet, and the Wi-Fi network to connect with a PC (through a router with a fixed IP) to view topics and carry out basic control of what happens in the ROS environment.

What I'm not sure is:

• This is a network configuration problem right? Any idea how I can solve it?
• Should I solve it at the node level (some python library may be)?
• Is there a ROS package that allows me to address this particular node to the 4G connection and keep the rest of the ROS system addressable on the WIFI network?

THANKS IN ADVANCE, any tip helps me to keep moving forward
