Yes, standalone. No other gateways/routers/switches/etc. on the system. Basically, I would just use this for filesharing for machines off of the DSL-equipped network.
Thanks for the response. Just to clarify, though, will this only work with DCHP on the connected machines? Not that I would need to do so with the setup described above, but are you saying I won't be able to specify IP addresses for the connected machines (192.168.x.x)?
