Traffic Shaping data link Fortigate 5.4

[Tequeterequeteque]

Hi, can anybody help me achieve this:

I have a private data link from another branch of my bussiness, that data link have a 30Mbps bandwith to my site, and we propvide internet to them.

I want to give each applicable user/device 3 Mbps of bandwith but I would also like to set 30 Mbps to that remote branch so they wont collapse the link.

So for example, I want to give each address on the 192.168.0.0/24 pool 3Mbps, but give all that 192.168.0.0 network 30Mbps shared.

Another way to explain

Remote Branch. 30Mbps Total shared between every single user connected to it

Remote branch user: 3Mbps maximun (and even If I have 20 users using all their bandwith they can no reach the 30Mbps set for that branch)

Thank you
