Topic: PPTP and Macintosh clients

[BrianB]

Has anyone setup a Macintosh with PPTP and 4.1.2 or 5.0?

I have tried NTS TunnelBuilder for Mac (full version) and all I get is errors.

On the Mac side the first error is an alert box saying "Authentication with the VPN server has failed." and the logs are;
2/19/02 21:30:11: CHAP: received CHAP challange for host "e-smith"
2/19/02 21:30:11: CHAP: authentication failed, host says "I don't like you. Go 'way."
2/19/02 21:30:11: VPN: disconnect 0 1

And on the 4.1.1 box with pptp set to 5 the logs are(tail /var/log/messages);

Any Ideas?

I have tried on newly created users names and passwds, and with root and admin.

Using root and admin the log on 4.1.2 is;

Feb 19 21:45:59 e-smith pppd[3375]: No CHAP secret found for authenticating root
Feb 19 21:45:59 e-smith pppd[3375]: CHAP peer authentication failed for remote host root

The Vendor says its an server problem;
I provided the logs and it looks like a pass the buck response.
