Do you have any traffic shaping configured?

On my shorewall firewall 5.1.10.2 on Centos 7 up to date I
have change ADSL providers from 30 Mbit/s to 900 Mbit/s

On the shorewall server with all network adapter 1Gb with
speedtest-cli I get the real speed (near 900 Mbit/s), but all PC
and Notebook with 1 Gb nic adapter on LAN that pass through the
firewall, get a slow speed test (<90 Mbit/s).

I have also try to connect a Notebook direct to server LAN
network adapter to bypass the switch but none is change, speed
is <9x,00 Mbit/s.

Insted if I connect the same Notebook direct to router the
speed test go to 900 Mbit/s

Seem
that the firewall pass through limited the traffic speed to 100
Mbit/s

Someone can suggest me what I can check in order to resolve
this issue?

Many thanks to All
