Hi guys,

I have a problem. I = have a=20 client (192.168.9.2) that send TCP segment to a server = (192.168.11.2).=20 Between this PC there is a Linux router that captures all the = segment=20 and do forwarding. I want that it takes a client packet (the 10th TCP = data=20 packet sended, for example), modify it as i want, and then resend it to = the=20 client with ipq_set_verdict.

Is this operation possible? Or = netfilter=20 can only send the modified packet at the server? If it's possible, = which=20 field must i modify to do this (i've tried to modify some flag but it = doesn't=20 work)?

Thanks for your help

Best regards
