Hi, I want to forward a packet modified by libnetfilter_queue. In detail, suppose a TCP packet is delivered from host1 to host2 as followings. host1 ---> server --> host2 Here, a server is connected both to host1 and to host2. (to two NICs) First, host1 sends a TCP packet for host2. When a packet comes into server, the server modifies the packet(header or payload). Then, the server forwards the modified packet to host2. ---------------------------------------------------------- I know how to intercept incoming packet at a server by iptables and netfilter_queue, but I don't know how to forward the modified packet to host2. In detail, I create a NFQUEUE using iptables and I use modified "nfqnl_test.c" to intercept and modify a packet. Problem is how to forward the modified packet to an original destination of the packet (In above scenario, to host2) Should I add some filter rules with iptables or should I add some codes in "nfqnl_test.c" ? Any suggestions would be helpful for me. Thanks in advance.
