I have configured VPN3030 to hold an PPTP endpoint for internet user to access. I have added a group and user with PPTP settings. But the user cannot successfully establish the PPTP tunnel. They failed to connect to VPN endpoint with an Error691(WindowsXP).The event log on VPN3030 seems to inform that it can only use radius to authenticate user and does not try to use its internal user DB when the user does not exist in radius. The configuration of the authentication server in VPn3030 is set to be Radius as first server and Internal as secondary server.
So why does the VPN3030 not try to authenticate user using the secondary server(internal user DB)?
Additionally, this VPN3030 is now holding another PPTP settings with Base Group settings. It will use Radius to authen users and use the address Pool which is in "Configuration | System | Address Management | Pools".
