I can only guess that there is a problem with "unknown" protocols like gre (haven't checked on esp, and so forth). Using the protocol number (in this case 47) also fails. I'm using libnfnetlink-0.0.40 and libnetfilter_conntrack-0.0.99 Kernel version 2.6.29-rc7. The conntrack version is that released on the website (md5sum: ae97d335ad44e9611adde881490c8ec9). All that appears correct. -Bryan
