Ok,
So yesterday I needed to use a small program to rewrite packets flowing
through my transparent bridge. I started using the an ipq
implementation and after a bit of jiggery pokery fixing up all the
checksums, it seemed to be working a treat. I then knocked up an
nfqueue implementation using the code I'd been writing that did exactly
the same job, and using the the subversion copies of libnetfilter_queue
(0.0.12) and libnfnetlink (0.0.16), I did manage to mangle the packets
successfully...
I still don't seem to be able to send out packets with a broken
checksum, but I haven't yet verified whether that's the target end
dropping them or the linux kernel killing them before they get on the
wire. I hope this helps...
