Packet trace examples

I am trying to make NAT decisions in an nfqueue, but given this is not
supported as a verdict in queues, what I am doing is this:
- Accept and set a packet mark in the nfqueue
- In a lower priority base chain, apply the dnat rule if the packet has the
apprpriate mark

Thing is the marked packet from the nfqueue never hits the second base chain.

If I accept with a simple rule, I can see it hit the next base chain as
expected

Oddly I have done something similar in inet filter forward chains and there it
works just fine.
