To flush your iptable rules you can run:
/sbin/iptables -F
-F, --flush [chain]
Flush the selected chain (all the chains in the table if none is
given). This is equivalent to deleting all the rules one by
one.
If you only want to flush one chain (e.g. OUTPUT) then run:
/sbin/iptables -F OUTPUT
Running /sbin/iptables -L -v -n before and after will show you what rules are
there and what are deleted.
Iptables scripts usually run --flush to clear out any previous rules before
they add their own.
You can edit any such script to add the MASQUERADE target I suggested
previously in the POSTROUTING chain (following the syntax of the particular
script).

... and I bet that the routes do not look like what you posted in your first
message.
Your current routes are not correctly configured. The fact that it is trying
to use eth0 may be related to the ethX number? i.e. it starts from the lowest
number and it works it's way up. You can delete your net udev rules and
reboot to change these (or manually edit your udev rules). Either way, adapt
my previous instructions for your respective NIC numbers.

It looks like a well spec'ed single port modem and ADSL router. Since it is
running a DNS repeater you can set in your /etc/resolv.conf files the IP of
your router as the DNS server - if it doesn't pick it up on its own.
