I have an existing Netgear cable modem and router connected to several hard-wired internal network devices. I recently added the M5 (OK, today) and set it to AP mode so that devices joining through this network have access to the internal network.
I want to include a guest network on the M5, but was wondering about the mechanism by which it protects the parent's (Netgear) internal network in AP mode. I tested it out and it looks like I can access the web interface on my router, but nothing else. How's that work? Save for the http connection to the Netgear router, is everything else on the parent network (NAS, PCs, etc.) protected?
