Sharing DSL through router

I have a network sharing through a Linksys router. I am using DSL to access the internet through the router. I have a standalone PC which is using dialup. I want to add the standalone PC to the router so that I can access the internet using the DSL.I do not want the standalone PC to be part of the network. Can i do that by connecting the PC to the router? Or will that PC become a workstation on the network?
