Please see some strategies for resolving and troubleshooting this issue in my answer here. You shouldn't need to set ROS_IP on the MATLAB machine, as MATLAB does that for you, though it can't hurt to try. More important is to set it on the remote nodes before running them. Also see Ines' suggestion about the firewall on the same page.
