Trouble setting QUEUE in mangle table

Trouble setting QUEUE in mangle table

[joel williams]

Could use some advice.
I have a user space program and want process all packets coming into the
box (PREROUTING) and going out of the box (POSTROUTING).

POSTROUTING works as advertised, but I can not get PREROUTING,
INPUT or OUTPUT hooks to send  the packets the user program.

I am adding a QUEUE rule to the mangle table. (Seems to behave the same 
on filter table also.)
No other rules are defined.

Any ideas what might be wrong?

This works, sends packets to userspace program:

This does no work, processes packets normally, ignores rule
