Ok you getting a dhcp addy here?  Look at "system-config-network" your
not getting a proper gateway or dns entry.  You will have to probaly
define it manually as I've come to find out with many cheap routers or
either this is a bug in linux.  Use "route" to check for the DFG.

If you Bridge the DSL to function as a Modem Only it does not matter
that goes out the window.  It's no concern when your  in Routing Mode
with the other.  But you can not have two same ips defined as your
seeing so the bridge needs one for management and the router a different
one. So one has to be changed.
