PPTP Server help

RouterOS General
1

Hey All,

I’m trying to setup a PPTP server. I want to be able to authenticate to RADIUS. How do I set that up? I’m already using pppoe on this box and authenticating to radius just fine. I’m a little stumped on how to set this up for PPTP. PPTP ignores my current radius setup and there is no option to set my service=PPTP in (/radius). Any ideas or suggestions would be appreciated! Thanks.

the same way as pppoe. As ‘service’ value you should specify ppp.

I’ve tried that with no luck. How do I set the mikrotik to use the second ppp service for pptp and not to use the first ppp that is for pppoe?

they are all in one (ppp-kind). The same like you are using ‘/ppp’ menu in the router. Use the same RADIUS server as for pppoe. If the same problem appears, post the following printouts - ‘/inter pptp-ser serv pr’,‘/ppp aaa pr’, ‘/ppp prof pr’,‘/radius pr’.

and ‘/ppp profile print’? Maybe take a look in the RADIUS server’s logs. Try to run it also in debugging mode and see what kind of information is sent to the RADIUS server in the moment of authentication.

I have been running my radius in debug mode. I do not receive any radius packets. However the Mikrotik log complains of a radius timeout?? That’s what made me think I had a configuration issue.

make sure that IP of the RADIUS server is 205.162.25.85 and the secrets should also be equal.

they are. RADIUS works flawlessly to the same pppoe server. It just doesn’t work with the pptp-server, I never receive any radius requests and mikrotik logs a ‘radius timeout’ message.

please, make a support output file (right after you are were trying to connect some pptp man) and send it to support@mikrotik.com
