Cisco IOS router with ADSL: NetFlow collection

Cisco IOS router with ADSL: NetFlow collection

Hi,

I am trying to collect Net Flow statistic from Cisco 1841 router. The router is connected to the internet using Cisco ADSL HWIC. The connection is made using Dialer interface. Net Flow Analyzer detects all interfaces of the router correctly.

My problem is:

for "Dialer" interface only OUT traffic is shown
for "Virtual-Access" interface only IN traffic is shown

all other interfaces are shown as expected.

Each interface has NetFlow enabled:

show ip flow interface
FastEthernet0/0
ip route-cache flow
ATM0/0/0
ip route-cache flow
Virtual-Access2
ip route-cache flow
Dialer0
ip route-cache flow










Any advice would be much appreciated.
