If you have a router, then the ADSL connection you have is handled by
the router, and is invisible to you, on the LAN side of the router. The
router could be connecting to the WAN via a piece of wet string, as far
as you care. So you should just have eth0 do DHCP and leave it connected
to the router. You'll get an address like 192.168.1.2 from the router.
You don't need ppp0 at all; to Centos the router appears like a LAN that
routes to the Internet.
In Windows, do "ipconfig" in a Command window, and you'll see what I
mean. You should see something similar with ifconfig in Centos.
