I'm using an Ubiquity Edgerouter Pro PoE with exactly this configuration. I'm not saying it's the best product for this purpose, but I have used it in this way for several years now. My main complaint about the model I have is that you only have hardware switching on the first two ports, making the remaining ports somewhat useless as the CPU isn't fast enough to route more than a few hundred Mb/s.
