How to deny everyone access except certain hosts and IPs with Apache 2.4?

I've read the first results in google and Apache 2.4 docs and there is no clear example.

Currently this works (from 2.2) in a .htaccess file, I can access within the office wifi/LAN but not from my mobile/cell network:

Order deny,allow
Deny from all
allow from 123.123 example.com

I want the same using 2.4, so I tried:

Require ip 123.123
Require host example.com

And even:

Require ip 123.123
Require host example.com
Require all denied

And even changing the order of the lines, with denied at the top. Still can't get it too work, I can manage to access the page from my mobile/cell network.

What have I missed?

PS - AllowOverride All in the directory conf and the deprecated commands work, but not the new 2.4 stuff.
