Inquiry Regarding Per-IP Shaper in Traffic Shaping on FortiGate Firewall

[F-ALI]

Dear Team,

I have a question regarding the use of the Per-IP Shaper feature in traffic shaping on the FortiGate firewall.

I configured a traffic shaper with a total shared bandwidth of 20 Mbps (Reverse enabled) for 10 users.
Additionally, I applied a Per-IP shaper limit of 4 Mbps.

My inquiry is:
Does this configuration mean that all 10 users combined can consume up to 40 Mbps (i.e., 4 Mbps per user), or will the total bandwidth still be limited to 20 Mbps regardless of the Per-IP shaper setting?

Looking forward to your clarification.

Hi,

as far as I understand traffic shaping on FortiGates it's the following behavior:

The total bandwidth is limited to 20 Mbps across all users, regardless of the 4 Mbps Per-IP limit.

-  Per-IP Shaper ensures that no single IP address can exceed 4 Mbps and the Shared Shaper ensures that all users combined cannot exceed 20 Mbps.
