yes, it is possible. I have not done it myself, however I have seen it. The linksys router
obviously will be connected to your LAN possibly running DHCP, and the WAN conection to the DSL. To verify the dsl, install it directly to a pc and run winpoet 2.0 . You will need to know the login username and password . ( This setting will also be needed in the linksys router as well to authenticate ). Good Luck !!! #-)
