iptable forward packet

Hi,
I have the doubt which involved following configuration.
comp1<--->main<--->comp2
Comp1 sends icmp packet to main. Main takes that packet and changes destination address to comp2 and source address to it own.
I can capture the packet send from comp1 to main using netfilter. I can see the packet and its content. Then i modify the destination, source address and ip checksum successfully. But when i release it back to the kernel the packet never goes back to comp2. To release back packet i use nfq_set_verdict(....,NF_ACCEPT). If i capture packet from output chain of main when its sending ping reply back to comp1 my program modifies that packet and sends it to comp2 but if i capture packet from input chain of filter table than it does not forward that to modified address. I think this maybe because once the packet is in input chain of filter table modifying destination address means nothing. Can someone assist me how to forward packet from comp1 to comp2 through main.

NAME
kismet_drone - Wireless sniffing and monitoring remote drone SYNOPSIS
kismet_drone [-svh] [-f config-file] [-c capture-source] [-C enable-capture-sources] [-p port] [-a allowed-hosts] [-N server-name] DESCRIPTION
kismet_drone supports all the capture sources available to Kismet. Instead of processing packets locally, kismet_drone makes them avail- able via TCP to a remote kismet_server using the 'drone' capture source. USAGE
kismet_drone should be configured as you would kismet_server. All logging, packet dissection, etc will take place on the remote kismet server using the 'drone' capture source. kismet_monitor should be used to place capture sources into rfmonitor mode as needed, and kismet_hopper should be used for channel hopping. kismet_drone is controlled by the kismet_drone.conf config file. ENCRYPTION
It may be desireable to encrypt the packet stream between the remote drone and the kismet system. Standard SSH packet tunneling or any other tunneling/forwarding system may be used, and is recommended. SEE ALSO
