How to control a wpa_supplicant client request can only send to a hostapd NAS?
My network struct was following: RADIUS(freeradius) | | SWITCH(cisco) | | ------------------------------------------------ | | NAS1(hostapd) NAS2(hostapd) | | CLIENT1(wpa_supplicant) CLIENT2(wpa_supplicant) If the network only has the NAS1 device, the CLIENT1 can pass the authentication. When the network have two NAS device, which one is NAS1 and the other is NAS2, the CLIENT1 request can send to NAS1 and NAS2, then NAS1 and NAS2 all send the request to radius. I don't know whether CLIENT1 under NAS1 or NAS2 in radius. How to control a wpa_supplicant client request can only send to a hostapd NAS? Thank you very much!
