PPTP VPN Problem

I am using Debian OS with pptpd. My clients (both Windows and Mac) cannot complete the connection.

The following shows in syslog:

PHP Code:

Here is my pptpd-options file:

PHP Code:
#mtu 1490
#mru 1490 
When I watch the activity of the ppp0 interface which comes upon the connection, I see no activity at all.

Please advise. Thanks !
