Debian firewall+speedtouch bridge=no internet

[mousi]

Hello, I am trying to set up a debian sarge firewall/router. I have installed shorewall for this. Now I would like to put my speedtouch in bridge mode and connect with pppoe from the debian:
This is my my network:
LAN --- (eth0) DEBIAN (eth1) ---- Speedtouch ----- Internet
LAN is 192.168.1.0/255.255.255.0 and it is connected on eth0 of the debian box. Speedtouch is 10.0.0.0/255.255.255.0 and it is connected on eth1.

So, I managed to put the Speedtouch in bridge mode, i connected debian with pppoe, but i don't know how to setup the /etc/shorewall/masq and /etc/shorewall/interfaces files.

I've tried this in masq
ppp0 eth0
also
eth1 eth0
and in interfaces:
net ppp0 - routefilter,tcpflags,nobogons
loc eth0 detect dhcp

and also:
net eth1 detect dhcp,routefilter,tcpflags,nobogons
loc eth0 detect dhcp

Nothing works... What should I do?

PS: I would also like to setup QoS. What should I use for this?

thx in advance!

I am trying to follow where you say the problem is...can you get your new shorewall distro to connect to the internet? The issue is that users BEHIND it can't receive internet?

The shorewall distro gets ip from my provider (ppp0), but it can't ping www.google.com, so I guess it doesn't get the nameservers. I saw that right now...
