I was looking at using the RUT955, but I'm not married to that one in particular. I've used one in the past for testing and I like it.
Topology is a simple star. A main hub with 6 branches.
Using that article as a model, could I have a RUT955 at the main site, and then add 6 more remote sites (RUT955s) and all the PCs on the internal networks would talk to each other?
