Hi, marguedas I'm trying the similar thing, to get ros2_talker in my host to send messages to ros2_listener in virtualbox. Host: macOS, using ROS2_beta1 VBox: Lubuntu16.04, using ROS2_beta2 I used the "Bridged" network setup on VBox and I was able to ping them on both sides. I tried export ROS_DOMAIN_ID=42, but it doesn't seem to be working in my case. Do you have any ideas? --- [Visit Topic](https://discourse.ros.org/t/how-to-run-example-talker-listener-on-2-machines-with-different-ipaddr/2106/4) or reply to this email to respond.
