Dear friends, I am new to iptables and libipq. Please somebody reply to this query Is it possible to change both source and destination field in an IP header in PREROUTING. If not, plz somebody suggest me a way to do that. Let me explain in detail Suppose there are 3 machines A B C. When a packet comes from machine A to machine B. I would like to capture these packets AT MACHINE B BEFORE it goes through routing decision. I would like change the source and the destinatio IP address(modified SOURCE IP = MACHINE B IP, modified DESTINATION IP= MACHINE C IP) including the payload, and then pass it to the routing decision unit. Is it possible to implement this using iptables ? if yes,plz let me know. If not, then plz suggest some ways to do this. Thanx in advance
