Just to have a better clarification, you need two separate nodes to communicate using Connect Direct.
- You need to have Connect Direct Client and server installed on both the systems.
- In the netmap of node 1- add the IP and port of node 2 under remote node and similarly in the netmap of node 2, add the IP and port of node 1.
Secondly - in the userconfig file, add the user proxy- any user from remote node or specific user from remote node can submit jobs/process to the local node.
Note- by default IP is 1364, make sure firewall is open between the two nodes.
Try going through the installation guide it has this information detailed out
