Why can't SwarmAgent share work with other Agents?

Tried the above setup. Machines get registered to the coordinator but still don’t distribute the jobs. No custom build of the Swarm tool is required, no?

Any ports need to be open between machines to allow this to happen?

To add that I can’t ping any external machines from a client - but they are all listed in the coordinator.

Our current lighting builds are taking 12 hours - which isn’t ideal from a design iteration standpoint!
