Your topolology is odd. IF you want cero to provide rate
limiting/AQM/Qos, it has to be next to the adsl router, not where it
is. Assuming you want to keep it where it is....
If your firewall is running a recent linux, the cerowrt's aqm scripts
can also work there.
As for routing, the adsl box needs be configured to forward
192.168.1.0/24 and 172.30.42.0/24 to the firewall box, which needs to
also forward 172.30.42.0/24 to the cerowrt box, and you need to nuke
Easyest way to do that is to delete all but the top 3 firewall rules
on cerowrt, making them all be "FORWARD", editing
/etc/quagga/babeld.conf to allow ge00 as a babel interface, and
installing babeld on the firewall box. (you'd still need to tell the
dsl router to forward at least those two nets to the firewall box)

/etc/config/firewall sets up NAT. In your case, however, with your
topology, I don't see the need for any firewall rules at all.
