ros galactic map_server over network

edit

I am running nav2_map_server and AMCL on one computer in a network (Autonomous Mobile Robot) and run RVIZ2 on another computer (laptop workstation). Both machines are running ROS Galactic. All tf and static_tf messages are reaching the workstation, as well as the laser scan messages, etc. The /map topic is not reaching the workstation. I am sure the map topic is being published because I can echo the topic while connected to the AMR through SSH. The map even shows up on RVIZ2 on the AMR. It just doesn't reach the workstation. Has anyone had this issue before? Please give me some hints on how to fix this. Thanks for your time.
