Ok thanks.
What are these rules doing exactly?
Is there a way to change the network type manually whenever I want?
The rules allow for basic file and printer sharing on Microsoft/Samba networks. The rule is based on the Network Zone identified when CIS was installed, Usually, this is something like:
192.168.1.x/255.255.255.0
Although there are variations.
If you want to change the rules, you can modify the network zone or edit the rules directly.
