Rviz on remote computer

[Jarne-Rius]

Hi,
Instead of using the rviz on the Limo I would like to use the network to share the rosmaster with my PC. Online I found out that it is possible. I followed this guide as well as online help: Networking Multiple ROS Machines. But after trying to change the ROSMASTER with the ROS_MASTER_URI and ROS_IP. But I can see the topics from the limo but that is all. I don't get any updates from the Limo. If I check on the Limo I can see that it publishes on the topics.

The Limo has the IP: 10.10.10.236
and the pc has the IP: 10.10.10.10

So on the Limo I did this:
export ROS_MASTER_URI=http://10.10.10.236:11311
export ROS_IP=10.10.10.236

On my PC I exported this:
export ROS_MASTER_URI=http://10.10.10.236:11311
export ROS_IP=10.10.10.10

Also I changed the /etc/hosts on both, on the pc I added the ip from the limo. and on the Limo I added the ip from the PC

Is there anything I missed? because as I mentioned I can see the topics but I can't publish anything (from my PC) and I can't see the published data.
