CaptivePortal Problem Bandwidth with Squid Cache Server

[reza3sw]

Hello to friends
I've enabled PF Sense, CaptivePortal, along with FreeRADIUS, and I've defined a number of users in FreeRADIUS with bandwidth constraints.
I've also enabled SquidCache.
So far everything works right.

The problem is that if I download a file such as 100 MB, then this file is stored in the Squid cache, and if I download the same file from another system, I will download it from the Squid cache, but the point This is where the bandwidth I defined for FreeRADIUS user receives the file and gets very slow.

For example, I have defined a bandwidth of 400Kb / s
The user with the same bandwidth can download the file from the cache.

Is there any way that CaptivePortal can download it from a cache that is internally downloaded at an unlimited speed and only put bandwidth on the WAN?
