nfq_filter

Tool for HTTP packets filtering via nfqueue.

Requirements:

• kernel nfqueue support
• libnetfilter_queue >= 1.0.1
• modern gcc compiler with C++11 support

Install

$ git clone https://github.com/ircop/nfq_filter.git
$ cd nfq_filter
$ mkdir build && cd build
$ cmake ../
$ make
$
$ cp nfq_filter /usr/local/bin/nfq_filter

Install with nfqueue < 1.0.1

Open file nfq.cpp and replace two lines:

--              size = nfq_get_payload(nfa, (unsigned char **)&full_packet);
--              len = nfq_get_payload(nfa, &data);
++              size = nfq_get_payload(nfa, (char **)&full_packet);
++              len = nfq_get_payload(nfa, (char **)&data);

Usage

• Set iptables rule:

    iptables -t mangle -A PREROUTING -s x.x.x.x/y -p tcp -m tcp --dport 80 -j NFQUEUE --queue-num 0 --queue-bypass
  

  where x.x.x.x/y is source network (users) for http-requests filtering

• Edit config file ( /etc/nfq/nfq_filter.cfg ), at least set queue to capture and redirect url.

• Run program (or use init.d runscript in 'contrib' dir)
