Summary

RADIUS, short for Remote Authentication Dial-In User Service, is a remote server that provides authentication and accounting facilities to various network appliances. RADIUS authentication and accounting allows the ISP or network administrator to manage PPP user access and accounting from one server throughout a large network. The MikroTik RouterOS has a RADIUS client that can authenticate for HotSpot, PPP, PPPoE, PPTP, L2TP, OVPN, and ISDN connections. The attributes received from the RADIUS server override the ones set in the default profile, but if some parameters are not received they are taken from the respective default profile.

The RADIUS server database is consulted only if no matching user access record is found in the router's local database.

If RADIUS accounting is enabled, accounting information is also sent to the RADIUS server default for that service.

Enum parameters:

accounting-backup - Radius accounting backup

(string; Default: )	The shared secret used to access the RADIUS server.
service (ppp\|login\|hotspot\|wireless\|dhcp; Default: )	Router services that will use this RADIUS server: hotspot - HotSpot authentication service login - router's local user authentication ppp - Point-to-Point clients authentication wireless - wireless client authentication dhcp - DHCP protocol client authentication (client's MAC address is sent as User-Name)
src-address (ipv4/ipv6 address; Default: 0.0.0.0)	Source IP/IPv6 address of the packets sent to the RADIUS server
timeout (time; Default: 100ms)	Timeout after which the request should be resent, for example, "/radius set timeout=300ms numbers=0"

Note

When the RADIUS server is authenticating the user with CHAP, MS-CHAPv1, MS-CHAPv2, it is not using a shared secret, the secret is used only in the authentication reply, and the router (RADIUS client) verifies it. So if you have the wrong shared secret, the RADIUS server will accept a request, but the router won't accept the reply. You can see that with "/radius monitor" command, the "bad-replies" number should increase whenever somebody tries to connect.

Warning
If RadSec is enabled, make sure your RADIUS Server is using "radsec" as the shared secret, otherwise, the RADIUS Server will not be able to decrypt data correctly (unprintable characters). With RadSec RouterOS forces the shared secret to "radsec" regardless of what has been set manually. For more details see - RFC6614.

Example

To set up a RADIUS Client for HotSpot and PPP services that will authenticate against a RADIUS Server (10.0.0.3), you need to do the following:

Code Block

language	ros

[admin@MikroTik] > /radius add service=hotspot,ppp address=10.0.0.3 secret=ex
[admin@MikroTik] > /radius print
Flags: X - disabled
# SERVICE CALLED-ID DOMAIN ADDRESS SECRET
0 ppp,hotspot

To set up a RADIUS Client with RadSec, you need to do the following:

Code Block

language	ros

[admin@MikroTik] > /radius add service=hotspot,ppp address=10.0.0.3 secret=radsec protocol=radsec certificate=client.crt
[admin@MikroTik] > /radius print
Flags: X - disabled
# SERVICE CALLED-ID DOMAIN ADDRESS SECRET
0 ppp,hotspot 10.0.0.3 radsec

Note
Make sure the specified certificate is trusted.

To view RADIUS Client statistics, you need to do the following:

Code Block

language	ros

[admin@MikroTik] > /radius monitor 0
pending: 0
requests: 10
accepts: 4
rejects: 1
resends: 15
timeouts: 5
bad-replies: 0
last-request-rtt: 0s

Make sure you enable RADIUS authentication for the desired services:

Code Block

language	ros

/ppp aaa set use-radius=yes
/ip hotspot profile set default use-radius=yes

Connection Terminating from RADIUS

Sub-menu: `/radius incoming`

This facility supports unsolicited messages sent from the RADIUS server. Unsolicited messages extend RADIUS protocol commands, that allow terminating a session that has already been connected from the RADIUS server. For this purpose, DM (Disconnect-Messages) is used. Disconnect messages cause a user session to be terminated immediately.

Note
RouterOS doesn't support POD (Packet of Disconnect) the other RADIUS access request packet that performs a similar function as Disconnect Messages

Properties

Property	Description
accept (yes \| no; Default: no)	Whether to accept unsolicited messages
port (integer; Default: 1700)	The port number to listen for the requests on
vrf (VRF name; default value: main)	Set VRF on which service is listening for incoming connections
