Allow custom RADIUS NAS-ID 7.2.4

This information is also available in the FortiWiFi and FortiAP 7.2 Configuration Guide: Custom RADIUS NAS-ID

This enhancement allows users to configure the RADIUS NAS-ID as a custom ID or the hostname. When deploying a wireless network with WPA-Enterprise and RADIUS authentication, or using the RADIUS MAC authentication feature, FortiGate can use the custom NAS-ID in its Access-Request.

New CLI:

config user radius
  edit < server >
    set nas-id-type { legacy | custom | hostname }
    set nas-id < custom ID >
  next
end

You can configure nas-id-type with the following three options:

legacy	NAS-ID value is the value previously used by each daemon. This is the default setting.
custom	NAS-ID value is customized. Set nas-id to enter the custom ID.
hostname	NAS-ID value is the FortiGate hostname or HA group name if applicable.

To create an SSID with WPA2-Enterprise security mode using RADIUS authentication - CLI:

1. Configure the SSID:

    config wireless-controller vap
     edit "wifi7"
       set ssid "80F_ent_radius"
       set security wpa2-only-enterprise
       set voice-enterprise disable
       set auth radius
       set radius-server "server-55"
       set schedule "always"
     next
   end

2. Configure the RADIUS server:

    config user radius
     edit "server-55"
       set server "172.18.56.104"
       set secret ENC *
       set acct-interim-interval 60
       set radius-coa enable
       config accounting-server
         edit 1
           set status enable
           set server "172.18.56.104"
           set secret ENC *
         next
       end
     next
   end

3. Set the nas-id-type:

   config user radius
     edit server-55
       set nas-id-type hostname
    next
   end
   
   config system global
     set hostname "FortiWiFi-80F-2R"
   end

4. After the station connects to the SSID, check the radius packets to confirm the NAS-Identifier value matches the hostname FortiWiFi-80F-2R:

   (64) Received Access-Request Id 35 from 172.16.200.254:63111 to 172.16.200.55:1812 length 367
   (64)   User-Name = "tester"
   (64)   NAS-IP-Address = 0.0.0.0
   (64)   NAS-Identifier = "FortiWiFi-80F-2R"

To create a WPA2-Personal SSID using RADIUS MAC authentication - CLI:

1. Configure the SSID:

   config wireless-controller vap
     edit "wifi2"
       set ssid "80F_psk"
       set voice-enterprise disable
       set radius-mac-auth enable
       set radius-mac-auth-server "server-55"
       set passphrase ENC *
       set schedule "always"
     next
   end

2. Set the nas-id-type:

   config user radius
     edit server-55
       set nas-id-type custom
       set nas-id FWF-80F-LR
     next
   end

3. After the station connects to the SSID, check the radius packets to confirm the NAS-Identifier value matches the custom value you configured, "FWF-80F-LR":

   (87) Received Access-Request Id 3 from 172.16.200.254:62884 to 172.16.200.55:1812 length 228
   (87)   User-Name = "F1-A4-23-75-9F-B1"
   (87)   User-Password = "F1-A4-23-75-9F-B1"
   (87)   Calling-Station-Id = "F1-A4-23-75-9F-B1"
   (87)   NAS-IP-Address = 0.0.0.0
   (87)   NAS-Identifier = "FWF-80F-LR"
