vlan + ng_ipfw + ng_netflow == no success

[Eugene Mitrofanov]

Hello

I need the advise. Does anybody got the Subj working?

I have FreeBSD 7.3-p2, Generic kernel. I try to set up the netflow traffic 
accounting using ng_ipfw from vlan interface. I created vlan interface, ipfw 
rule, set up ng hooks but the netflow export is not working. tcpdump does 
not catch any packets to the collector. Any suggestion? Should I create the 
bug report?
