User Manager/PPP Example

Introduction

User Manager might be used as remote authentication, authorization and accounting server for PPP clients Note, only PAP and CHAP authentication methods supported by User Manager now. Let's consider configuration steps for PPP and User Manager routers.

PPP configuration

We consider PPPoE server <-> PPPoE client configuration example, when PPPoE server uses remote User Manager database for PPPoE clients authentication, authorization and accounting. Both PPPoE server and PPPoE client are MikroTik routers, any other PPPoE client might be used instead.

PPP server configuration

• First, add PPPoE server to the local interface, remember that User Manager server only supports PAP and CHAP authentication methods:

 / interface pppoe-server server add interface=ether1 service-name=MikroTik one-session-per-host=yes disabled=no authentication=chap,pap

• Specify to use User Manager for PPPoE clients:

 / ppp aaa set use-radius=yes

• Set IP address of the PPPoE server, IP address might not be assigned to the interface of PPPoE server. Moreover static IP address or DHCP are not recommended to use on the same interfaces as PPPoE server for security reasons.

 / ppp set default local-address=192.168.0.1

• Add radius client to consult User Manager for PPP service.

 / radius add service=ppp address=y.y.y.y secret=123456

'secret' is equal to User Manager router secret. 'y.y.y.y' is the User Manager router address.

• Note, first local PPP database is consulted, then User Manager database.

PPP client configuration

• Add PPPoE client to the interface

 / interface pppoe-client add interface=ether1 user=MikroTik password=MikroTik service-name=MikroTik allow=pap,chap

User Manager configuration

• First, you need to download and install User Manager package;
• Create User Manager subscriber;

/ tool user-manager customer add login="MikroTik" password="qwerty" permissions=owner

• Add PPP server information to router list,

 / tool user-manager router add subscriber=MikroTik ip-address=x.x.x.x shared-secret=123456

'x.x.x.x' is the address of the PPPoE-server router, 'shared-secret' should match on both User Manager and PPPoE-server routers.

• Add PPPoE client information,

 / tool user-manager user add username=demo password=demo subscriber=MikroTik ip-address=192.168.0.2

• Let's verify, that PPPoE client is connected and using User Manager for authentication, authorization and accounting. First we monitor if PPPoE client is connected, then we verify that User Manager used. First command is executed on PPPoE client router, second on the PPPoE server:

 / interface pppoe-client monitor pppoe-out1
       status: "connected"
       uptime: 12h2m29s
    idle-time: 12h2m17s
 service-name: "MikroTik"
      ac-name: "MikroTik"
       ac-mac: 00:0C:42:05:54:8F
          mtu: 1480
          mru: 1480

 / ppp active> print
