How to continue ?

I've got a shorewall to mount and I've read information about different
configurations but I don't know exactly how to do it.

The machine that I want to mount has 5 interfaces:

eth0.- Connected to a dsl
eth1.- Connected by vlan to three dsl
eth2.- Connected to a zone local a
eth3.- Connected to a zone local b
eth4.- Connected to a dmz

The idea is that all the traffic that comes from the interface eth2, be
load-balanced by the three dsl connected by vlan in eth1 (eth1.100,
eth1.101, eth.102). For this, I've read the article if Multiisp and with
interfaces on awake in the machine works perfectly.

The thing is that when I start waking up the next interfaces which I
don't know how to continue. The idea is that the rest of the traffic of
the interfaces (eth3, eth4) comes out from the eth0. Here is where I get
lost, and I don't know so much how to continue, I guess I have to define
eth0 as a provider in providers, but I don't know so much how to do it,
and I have thought in using route_rules with the option activate
HIGH_ROUTE_MARKS=YES in shorewall.conf.

route_rules
<verbatim>
eth3    -       providereth0    1000
eth4    -       providereth0    1000
</verbatim>

If i want to take out all the traffic that comes from the firewall to
eth0, it wil be only adding "lo" to the file of route_rules?

I'm using ubuntu 6.0.6 and the shorewall 3.2 from the svn.

Thanks in advance.
