Hmm, I didn't realise that ipsec_tunnel.h was used by userland at all :-(
I have pushed some changes for that.
Also the NF_IP_LOCAL_OUT is just a pain, depending on what order headers
are included in and whether or not you are using CentOS or a linux kernel
it's all over the place. Try the attached patch after pull that latest
changes to klips-ipv6.
I think that should do it, if not, let me know what kernel version you
I am running on 2.6.26 at the moment, but will try out 2.6.35 tomorrow
and make sure all is well,
