Hi,
I'm working with a QNX system based of 6.5.0.  I have access to the code and root access to the board but no reasons why
 things are done the way they are.

There is pf.conf on the board it appears the board is behaving like it is using it.  However  pf or bfp is not a running
 process. 
If I try this ...
pfctl -d -f /etc/pf.conf
pfctl: /dev/pf: No such file or directory

So what else on the system could be doing filtering?  What other commands can I run to see where the packet get eaten at
?

Thanks

Phil Deneau
