Individual bandwidth limit for users with same ip address

[jakanaka]

localhost
route /myroute {
    bandwidth {
        limit 100000
    }
}

Let's say i have set this limit and i have 3 users with same ip address. i want them each users to have a bw limit of 100000, totaling 300000, currently it limits total speed for a ip address. meaning 3 users total gets 100000.
