Does Collection Monitor send requests from my machine or from remote (not my) machine?

When I launch Collection Monitor, it encounters problems that I don’t encounter when I launch the collection manually. The system I’m testing is protected by firewall, and my local machine has the required access.

When I launch the Collection Monitor, I don’t get any response and monitor fails. Does it send requests from some remote server and thus failing? Is there a way to set up monitor to be run from my local machine?

It sends remotely.

I think you need to have Postman Enterprise, which allows you to have a dedicated IP which you can allow access through your firewall.
