Managing out of network computers redux

It was interesting to read

https://www-secure.symantec.com/connect/forums/how-does-one-configure-sepm-121-manage-out-network-computers

but it contained some links to technical articles that don't work any more.

Since the thread is locked the only thing ou can do is start a new discussion, so here we are.

Is this still possible (especially with Windows 10)?   Are there updated links to the content?
