I have a Belkin WiFi Router which offers a feature of a secondary Guest Access WiFi network. Of course, the idea is that the Guest network doesn't have access to the computers/devices on the main network.
I also have a Comcast-issues Cable Modem/Router device with multiple wired ports, but no WiFi capabilities. I prefer to only run one router/DHCP/NAT instead of both the Comcast Router and the Belkin Router, so I can disable the Routing functions of the Belkin and allow the Comcast Router to
But if I disable the Routing functions of the Belkin device, the Guest WiFi network is still available. Is this configuration just as secure as when the Belkin acts as a Router?
I guess the question comes down to this:
Do Guest WiFis provide security by
- only allowing requests to IPs found in-front of the device, or do they work by
- disallowing requests to IPs on the same subnet?
- Would mean that Guest WiFi on an access point provides no benefit, or
- Would mean that the Guest WiFi functionality can work even if the device is just an access point.
Or maybe something else entirely?
