[Nut-upsuser] Help with failing Nut slave/client connection

HI again, Sorry I didn't mean to cause a security debate.
I'd like things to be secure of course, but I've got a dilema that I don't
use DHCP and instead have a block of static IPs from my ISP.
So my nut server has 68.68.452.02 for example
and my two slave clients have 68.68.452.03 and .04
ideally I'd like to allow access for the whole static IP block to access
the nut server machine.
I've tried all sorts in the nut.conf upsd.users and other config files but
just can't get it to work.
Any advice or help would be really appreciated.
Thank you :)
