Thanks in advance for your help, I am running the demo test code (with queue num 100) nfqnl_test.c which is found in the documentation. http://www.netfilter.org/projects/libnetfilter_queue/doxygen/nfqnl__test_8c_source.html I have added the following rules to my iptables: sudo iptables -A OUTPUT ! --out-interface lo -p tcp --syn -j NFQUEUE --queue-bypass --queue-num 100 sudo iptables -A OUTPUT ! --out-interface lo -p tcp --syn -j LOG --log-level 7 There are many packets arriving at the LOG. But none ever arrive to NFQUEUE on the userspace side. recv(fd, buf, sizeof(buf), 0) just hangs waiting for the message from the kernel. The binding and creation of the queue seems to have gone fine, no errors were thrown before reaching this call. I am also running my program as root. My output of `lsmod`: http://pastebin.com/m3gBKVst Any tips to debug this are appreciated!
