I have a ZyXel GS2200-24 managed switch, and a free-radius server running on Ubuntu 11.10. Radius is configured and when I log into the switch the authentication goes through Radius.
Now, I'm trying to ensure that access to web resources (as an example, I set up a web server on the ip 192.168.1.2) requires first authenticating with radius, before the switch will allow the connection.
Am I correct that this should be handled at the switch level? What are these rules usually called / how are they usually defined?
My switch supports port based authentication, meaning you can require 802.1x authentication (or not) for each physical connection to the switch itself. You simply need to have a switch that supports this.
In the Zyxel Web Configurator, you can do this under Advanced Application > Port Authentication
