[TYPO3-calendar] Typoscript config shown categories + ip access check

[PM]

Hello

How can I set categories that are shown not inside the plugin but by 
using typoscript-setup.

Reason:

I want to show usern within the networks other categories than users 
from outside:

So I want to set something like:

[IP = 192.168.*.*]
categories = 1,2,3
[ELSE]
categories = 3,4,5
[GLOBAL]

what do i have to write instead of "categories = xxxx" ?

Thanks
