Zero access before user portal login?

Is it possible to enforce a portal only access where all domain visitors are required to log into the user portal before they can see/access anything including the admin login if they are granted access to it?

that sounds feasible, but why do you want to do that ?

now that i think of it i guess i could use a redirect for to sso as long as the underlying ffsync or baikal or whatever service would still be accessible. the tucked away admin login would be nice though. and to answer your question about why, its mostly thoughts on security.

I really don’t know much about all this stuff so i’m learning as a go.
