How to set up Limiter with slow LAN?

snitem

I have an internet connection with 250 Mbit down and 40 Mbit up. There are 4 apartments in this building, each connected to pfSense with a VLAN. However the LAN cables to the apartments are 100 Mbit only (4 wire cables, can't be changed).
My target is to minimize bufferbloat. How should I assign the limiters? Right now I have a FQ_CODEL limiter for my WAN only. Do I need additional limiters for the VLANS to account the 100 Mbit cables? Thanks.

@snitem so your looking what to limit each apartment to like 62.5/10 ?

Or is it ok for if say the 3 other clients not doing anything or apartment 1 to get 100, the limit of their wire is going to limit them to that.. Or even nobody doing anything else you still want to limit them to the 250/4 ?

@johnpoz It is ok for an apartment to use the full 100. Of course they are limited by the wire but bufferbloat is not looking good unless I set my WAN limiter to 100. But that seems impractical to me because it would not allow for two apartments use the full 100 each at the same time. I was wondering if I could limit my WAN to 250 and the VLANs to 100 or something like that to achieve good bufferbloat rating without wasting 150 of my 250 Mbit by limiting WAN.

@snitem

Limit every vlan (each for 1 appartement)
To 60 down and 9 up

Set the bloat limiter
On your wan with floating rule to the exact up / down you get for your wan connection

A fair method for all users
They have a 60/9 connection protected by a pfS

And you can also tweak the limiters with a time based scheduler

But be aware limiters on 2.6 CE
Are a bit well as far as I know not working
