Common Scenarios
Gargoyle is a tremendously flexible tool, and every situation is a little different - however sometimes an example is a good place to start.
Household with Teenagers and capped monthly Download
Scenario: The teenagers each have a mobile, a laptop, and friends; almost every month the Download cap is reached; the ISP has outrageous excess charges; and no-body knows where all of the the GB went.
Objective: Share Downloads fairly between family members.
Assign Static IP Addresses
Assign a fixed static IP address to each device (mobile, laptop, tablet etc) and keep the static IPs for each person together in a group.

Set Daily Quotas
Assign an equal share to each family member. For example: if the Download cap is 100GB/month then each family member could be assigned a quota of 100GB / 30days / 4people = 833MB/day. Round up to say 1GB/day.
