Think of Rule Sets as a Policy. In many contexts, that is what it is.
A Rule Set is essentially a collection of lists that are enabled, or not enabled.
Types of Rule Sets:
- Whitelist: Block all DNS queries, except for domains listed on a List which is also enabled.
- Blacklist: Allow all DNS queries, except block domains listed on a List which is also enabled.
- Unfiltered: Allow all DNS queries, and additionally allow re-direction of domains to be forwarded elsewhere (rainbow lists).
- Schedule: Follow the rules based on the pre-defined schedule (over a 1-week period).
