Using a CradlePoint router with ROS

I am working on a project that requires long range communication using a cell network. We have a 4G modem with a static IP address that is attached to a CradlePoint CTR-500 router. This router is then linked into the robot's computer through eth0. While the static IP address is in the 66._ _ _. _ _ _. _ _ _ range, the CradlePoint creates a LAN in the 192.168.0._ _ _ subnet, and this is what the computer views its IP address as.

I have a base station located far away that is connected to the internet. I can ping the USB modem from the base station, and the robot's computer can ping the base station, but I cannot connect to each of them through ROS. I imagine that I will have to set up some sort of port forwarding to get them to communicate.

If anyone has any suggestions on how I can connect the two computers through ROS, I would greatly appreciate it.

Thank you,

Go through the tutorials and there are tutorials on how to do that. Also double check your router's firewall isn't blocking the ports that ROS is trying to use.
