I hope to config my cisco 2611 router to support MPPE PPTP VPN
connection.
I configured my cisco router as below:
username user1 password 0 user1
aaa authentication ppp default local
aaa authorization network default if-authenticat
vpdn-group 1
! Default PPTP VPDN group
accept-dialin
protocol pptp
virtual-template 1
interface Virtual-Template1
mtu 1492
ip address 192.168.7.1 255.255.255.0
ip nat inside
peer default ip address pool PPTP_DIALIN
ppp encrypt mppe auto
ppp authentication chap pap ms-chap ms-chap-v2
!
ip local pool PPTP_DIALIN 192.168.7.109 192.168.7.113

when I tried to connect from my Win2k PC, I say below debug
information in Cisco router. Win2k just report an error : error 619,
the specified port is not connected.
