Re: libnetfilter_queue man page

Hi,

First, thanks for the documentation. It was helpful for me to understand the
code.

But, I still have a question : I would like to add an extension in filtered IPv6
multicast packets headers. Do you think, I can do this in the userspace
using libnetfilter queue ? And, how precisely does it work ? Is it something
like this :

1. Activate the hook NF_IP6_LOCAL_OUT with an iptables rule
2. Launch my software with libnetfilter_queue
3. Modify the header
4. Return the whole packet to netfilter

Do I have tocreate a specific kernel module ?

Thanks for your responses.

Regards,
Julien
