WickedGoat98 you mean the server is on your home network and the agents are in a VPS?
If this is the case, then regular "clearml-server" port forwarding is the only thing you need.
TCP ports 8008/8080/8081
Notice that on the agents you will have to specify the address of your home IP.
I would recommend using a host name and not IP, since the artifact/debug samles links will contain direct links into the file server, and it is always safer to have a host name rather than IP that can change.
Even just defining the host name on your /etc/hosts will work 🙂
