I am using Debian OS with pptpd
. My clients (both Windows and Mac) cannot complete the connection.
The following shows in syslog:

Here is my pptpd-options file:
refuse-pap
refuse-chap
refuse-mschap
require-mschap-v2
require-mppe-128
proxyarp
nodefaultroute
lock
nobsdcomp
noipx
#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 !
