thansk for ur response @lonetorus
i have installed as ur said, transparent bridge beetween my LB hardware and proxy server, also some read on documentation bridge QoS ZS
inet — LB HW — (eth01) ZS Bridge (QoS) (eth00) — Proxy — Switch
since i have 3 asimetric adsl, each 2 mbps DL, 512 kbps UP
i have set up like this, eth01 QoS global benwith is 6 mbps and eth00 QoS global benwith is 512 kbps, bridge00 is unchecked QoS
is it my QoS config correct ?
