Gargoyle is a tremendously flexible tool, and every situation is a little different - however sometimes an example is a good place to start.
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 a fixed static IP address to each device (mobile, laptop, tablet etc) and keep the static IPs for each person together in a group.

| Son-mobile | 192.168.1.81 | 
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.
| Bandwidth Quotas | |
|---|---|
| 192.168.1.50-192.168.1.59 | Max Total Download = 1GB/day | 
| 192.168.1.60-192.168.1.69 | Max Total Download = 1GB/day | 
| 192.168.1.70-192.168.1.79 | Max Total Download = 1GB/day | 
| 192.168.1.80-192.168.1.89 | Max Total Download = 1GB/day | 
|  All Hosts without Explicit  Quota's (Combined)1)  | Max Total Download = 100MB/day | 
Scenario: There is One Internet connection into a Student Share House and one of the Students is (always) a Gamer. When the Gamer is online the Download speed for everybody else sux.
Scenario: Every now and again some geek turns up, buys one coffee, sits in the back corner for 4 hours and the WiFi performance sux.
Objective: Limit the impact that an anonymous individual can have on performance
DHCP will assign an IP address to many anonymous devices coming and going

|  All Individual Hosts  Without Explicit Quotas  | Max Total Up+Down = 200MB/day | 
Limit the performance impact of one greedy customer on other customers.
