Limit login by Service

[JAHANZAIB SYED]

Just to share logic, may be incorrect but In Mikrotik I see following

  *   PPPoE > NAS-Port-Type = Ethernet
  *   PPTP  > NAS-Port-Type = Virtual

Now using your users table where information is stored, you can then create query to match if user is using the allowed service type.

Users table example:

mysql> describe users;
+----------+-------------+------+-----+---------+----------------+
| Field    | Type        | Null | Key | Default | Extra          |
+----------+-------------+------+-----+---------+----------------+
| id       | int(10)     | NO   | PRI | NULL    | auto_increment |
| username | varchar(64) | NO   |     | NULL    |                |
| srvtype  | varchar(16) | NO   |     | NULL    |                |
+----------+-------------+------+-----+---------+----------------+
3 rows in set (0.00 sec)

mysql> select * from users;
# this type will allow pppoe only
+----+----------+----------+
| id | username | srvtype  |
+----+----------+----------+
|  1 | zaib     | Ethernet |
+----+----------+----------+
1 row in set (0.00 sec)

Now edit /etc/freeradius/sites-enabled/default & paste following in `Authorize` Section [look for correct syntax & braces if required]


if ("%{sql: select from users where username = '%{User-Name}'}" != "%{NAS-Port-Id}") {
update reply {
Reply-Message = 'Error: You are not allowed to connect form this VLAN !'
}
update control {
Auth-Type := "Reject"
}
}

Now try to connect to users from different type service

(9)   } # if ("%{sql: select srvtype from users where username = '%{User-Name}'}" != "%{NAS-Port-Type}")  = noop
(9)   Reply-Message = "Error: You are not allowed to connect using this service type !"
(9) Found Auth-Type = Reject
(9) Auth-Type = Reject, rejecting user
(9) Failed to authenticate the user

More info is here which I wrote about  VLAN number allowance here<https://aacable.wordpress.com/2018/01/18/freeradius-with-mikrotik-part-9-restrict-user-auth-from-allowed-vlan-only/>/link
