the ROS_IP of the local node is: 11.8.0.2 I can do everything from the local side and rosnode list and topics displays the whole list. However, when a node in the field computer has to send message to a node in the local computer, then, it doesn't work.

Original report (archived issue) by michele hallak (Bitbucket: mhallak).
Hi, We have the following configuration: a named "C11_Agent" running in the field computer and a named "c11" node running on a local computer. The two nodes communicate with ROS. However, if the communication from the local to the field computer is working well and smooth, the communication from the field computer to the local has a problem. For example, on the field computer:
For sure, it shouldn't be local node but the node with ip 11.8.0.2.
I have no problem on the local computer accessing the ROS nodes running on field computer. We are running the trio constellation with all our nodes on the field computer apart of this specific node that needs to be on the local computer.
