no out traffic

Hi,

anyone help please..

I install netflow6 to monitor branch office traffic......
branch office several using frame relay and others using MPLS....

I enabled netflow both on serial and fastethernet port...
at NFA 6 webclient
fast ethernet port give in and out information
but the serial only give in information...no out traffic recorded

how is it can happenned??

we can aside traffic issue since netflow server can receive in and out traffic record from fast ethernet (NFA 6 web client give perfect result for fast ethernet in/out traffic)

here is the show run
