[Zope] Deny public access to ZMI

[Ustun Kaya]

Hello,

Is there a straightforward way of defining which IPs are authorized to
access to ZMI? I want to block public interface access and allow it
only from internal network - VPN. I don't want authentication box to
pop up to any single visitor with a browser.

It is Zope 2.9.4. As I searched, I came across with docs of how to
write scripts to define access rules to the specific folders. Should I
go that way and implement an access rule for /manage?

Thanks,
Ustun
