Hi guys, I have a problem. I have a client (192.168.9.2) that send TCP segment to a server (192.168.11.2). Between this PC there is a Linux router that captures all the segment and do forwarding. I want that it takes a client packet (the 10th TCP data packet sended, for example), modify it as i want, and then resend it to the client with ipq_set_verdict. Is this operation possible? Or netfilter can only send the modified packet at the server? If it's possible, which field must i modify to do this (i've tried to modify some flag but it doesn't work)? Thanks for your help Best regards
