How to Set Up WSUS Between Windows 10 Pro PCs

Microsoft has added a feature to Windows 10 pro insider preview that we can update our computers faster by getting updates from more than one place and choosing "PCs on my local network, and PCs on the Internet" option in Windows updates advanced settings. but this is vague. i don't know how this works! I have multiple PCs that have Windows 10 10130 pro Insider installed on them and updates are coming regularly in big sizes so I want to use this feature to update only one computer and let others get the updates just from that computer by choosing "PCs on my local network" in the settings. since some of the other computes aren't on the same subnet I want to know how to specify an Internal IP address for other computers on different subnets to find my computers and which ports do i need to open for this to work? I've seen many guides like this ()guide

but they are for Windows servers. Windows 10 has some options in group policy for specifying an intranet address to get updates from but i need to be sure if it works. does anyone have any ideas about how this works on Windows 10 machines? this is a nice feature added to Windows 10 and the RTM version is coming about soon but there is no guides on the web about it. Thanks in advance
