Cisco IOS PPTP Vpn traffic issue

Sascha Ferley

Hi,

I seem to be having a problem with one of our newer routers and utilizing PPTP.

The problem is that while the sessions connect fine, none of the traffic can route. It seems to work for about the first 3-5 seconds and then seems to drop all traffic while however staying connected.

The router is a 2811 ios version Advanced IP 12.4-9 T7

The config relating to pptp:

...

aaa new-model

!

!

aaa authentication login webvpn local

aaa authentication ppp default local

aaa authorization network default if-authenticated

!

aaa session-id common

...
vpdn enable
!        
vpdn-group 1
! Default PPTP VPDN group
accept-dialin
  protocol pptp
  virtual-template 1
..
interface Virtual-Template1
ip unnumbered FastEthernet0/0
ip mroute-cache
peer default ip address pool DIAL-IN
ppp encrypt mppe auto required
ppp authentication ms-chap ms-chap-v2
ip local pool DIAL-IN 10.10.10.230 10.10.10.240
..
Can someone help me debug .. i read somewhere it could be something related to "flow control alarm"
Please let me know
Thanks
