I followed all the instructions here, and even took some measures it failed to mention, but I still can't get matlab to talk to the ros1bridge in the ROS VM. The /etc/hosts files on host and VM both reference each other and I can ping both from the other, by hostname. The ROS_DOMAIN_ID has beeen set correctly. Environmental variables are set. The DEFAULT_FASTRTPS_PROFILES.xml file is in my project folder. And if I open a terminal on the host (outside of matlab), it will correctly display the topics from inside the VM.
So networking configuration is working; the only factor at play here is Matlab itself.
Within the Matlab terminal:
>> setenv("ROS_IP","192.168.93.1")
>> setenv("ROS_MASTER_URI","192.168.93.128")
>> setenv("ROS_DOMAIN_ID","25")
>> node = ros2node("/matlab_node")
ros2node with properties:
PING ubuntu (192.168.93.128) 56(84) bytes of data.
64 bytes from ubuntu (192.168.93.128): icmp_seq=1 ttl=64 time=0.172 ms

--- ubuntu ping statistics ---
3 packets transmitted, 3 received, 0
rtt min/avg/max/mdev = 0.099/0.125/0.172/0.033 ms
And from the VM, the matlab node is missing, but nodes I create on the host outside of matlab are visible.
Topics created on the host (but not in the matlab terminal), can be see inside both the VM and in matlab
