I wanted to modify the payload of packets in userspace, preferably with

however it appears that I am not able to divert properly. I cant find
any working examples of how to do the iptables command to divert.
Is there any other way to modify the payload of a packet from userspace,
preferably with perl?
can someone provide me with a working example of how to do iptables to
divert?
I have iptables 1.4.1.1 on eeebuntu (ubuntu base) and a kernel of 2.6.27
Thank you
Have you tried using NFQUEUE? The queue is provided to 'queue' packets
for userspace processing. To use the queue, you'll need the
libnetfilter_queue API. Start here:

If you need more help, let me know.
