Do you have a real IP address from the DSL modem, or does your Linksys do PPPOE?
If it's the latter, all of the IP traffic is being encapsulated within PPP--
ethereal should still see the traffic, but trying to match by IP addr will fail.
If you multihome the Linux machine, you should be able to do PPPOE on one
interface and sniff the traffic on the other...
