Configuring an Interface
The first thing you'll need to do is specify one or more interfaces for the radius server to listen on. The configuration settings for FreeRadius can be found under the services menu.
In most cases you will want to bind the service to the LAN interface.
1.Click on the interfaces tab of the settings page.
2.Click on the plus symbol icon to add a new interface.
3.Enter the LAN IP address in the Interface IP address field.
4.Click save
The rest of the settings can remain at the default settings.
