sophos xg - ip based traffic shaping

Hello all,

I have an xg210 v18. I want to shape traffic by ip address. I have a network 172.x.x.x 255.255.0.0 and don't have users so i cannot use match known users option. I want to shape traffic for each ip address like every one ip should have 5mbits speed. When i apply rule based individual traffic shaping the firewall gives 5mbits total for all users (pool) not for each user. I already tried application and web based traffic shaping but unfortunately result is the same. Can you please help me in this case?

Thanks in advance.
