Detect address range of user, restrict access based on that?

[DMahalko]

Is there a way for CMSMS to detect if the client is accessing the page from a specific address range?

We would like to create some "internal" pages which can only be accessed from within our NAT address range (example: net 192.168.1.0, mask 255.255.255.0), and which are denied access for external users outside that range.

Actually the ideal would probably be:
* Allow access without login for all of our local NAT users
* Require login/password for all WAN users


(Our CMSMS is used on Ubuntu with Apache. I know Apache can restrict page access based on the client address range, but I have no idea if this capability extends to CMSMS too.)
