starting Transmission at boot & webGUI

I am running 10.3 Gnome… I have added Transmission to startup at boot - I did this by right click>add to startup.

*I was hoping that once I booted the system that I would be able to use Transmission’s webGUI from a remote PC - but I am unable to connect.
*
I can connect though only if I login to the 10.3 box - Transmission is running on the desktop as I would have expected, I can then connect from the remote PC to the webGUI.

It is obvious that I misunderstand how this is to work - is there some other way to be able to do this?

Thank you…
