Hi,
frankly, I'm also surprised that the 'net_device *in' is NULL.
Probably there is much simpler way to do that than my idea, but have
you tried to mark somehow those packets in NF_IP_FORWARD and in
NF_IP_POST_ROUTING matching only those packets?
Another think... why do you want to match forwarded packets in
NF_IP_POST_ROUTING? I don't see the point, but presume that you know
what you are doing...

I must not fear. Fear is the mind-killer. Fear is the little-death that
brings total obliteration. I will face my fear. I will permit it to pass
over me and through me. And when it has gone past I will turn the inner
eye to see its path. Where the fear has gone there will be nothing.
Only I will remain.
Quoting Yakov Lerner <iler.ml@xxxxxxxxx>:
In the NF_IP_POST_ROUTING hook function, how can I
tell that packet originated locally vs was forwarded ?
I need to hook NF_IP_POST_ROUTING not NF_IP_FORWARD.
I'd expect that 'net_device *in' argument to be not NULL for
forwarded packets.
But what I see is NULL for both forwarded and locally sent packets
(in NF_IP_POST_ROUTING hook).
Which field of skb can tell me that packet originated locally ?
