PPTP VPN and external Radius Attributes

RouterOS General
1

Hello RouterOS-Pros,

could you shed some light on the following situation:

I’ve configured RouterOS PPTP VPN to use an external RADIUS-Server by Vasco. Auth seems to be working, but the Radius-Server seems to be missing
additional Attributes in his Response. I understand that i have to configure my Radius-Servers Dictionary with the appropriate RouterOS-Attributes. I’ve done that
by adding a dictionary file. My Questions are:

What are the required attributes to get PPTP VPN working with external RADIUS? Any Examples?
I just found the documentation explaining the RADIUS-Attributes, but which are the correct ones to use with PPTP VPN?

Thanks for your help

The only things needed as far as I know is local and remote addresses.

In the profile for the PPTP server, set a local address to be assigned to the server… Then in your RADIUS set the framed-ip-address attribute to whatever address you’d like the client to land on.

Chances have it it’s the local address that’s causing the server to bounce the connections. The server needs to know what address to assign to its local port for the connections.
